which are both obsolete and replaced in Openwrt by mainline
musl and glibc, which do not have a utils Makefile target.

Use the gcc/final/install target stampfile as the prerequisite
for the toolchain/compile target stampfile.
The previous filename was also incorrect,
the stampfile name format was changed (see reference)
but was never updated here.
The issue was never noticed
because the usage of timestamp.pl was broken
(fixed in previous commit)
causing the extra prereq files passed to 'call stampfile'
to never get checked at all.

This was apparently introduced to recreate the toolchain (wipe
staging_dir/toolchain*, but keep build_dir/toolchain*, followed by a
`make toolchain/compile`).
But it leaves leftovers and causes re-links to happen at src_install phase,
because of the changed paths, possibly adding yet another source of issues.
With the prior commits removing various hacks related to the "initial"
folder we can remove installing it twice altogether.
The recreated toolchain is exactly the same as before.

Instead of having two different ways to pass flags to the gcc build
process, add them as configure args, which is a reliable way to let
gcc pass them around to its various pieces.
Also add CXXFLAGS, since gcc started to use c++ for itself recently

Config evaluation require default with if to be put before the generic
default config with no condition. Putting the default config before any
conditional default results in always selecting the non conditional one.
This results in the version be hardcoded to gcc 12 even if gcc 11 is
selected in the Advanced build options.
Fix this by putting the gcc 12 default option as last after ANY
conditional default config.

This was build tested with all core packages on all targets
successfully.
Most packages from the feed are also building fine.
This was run tested on the following systems:
* lantiq/xrx200 musl
* pistachio/generic musl
* sunxi/cortexa53 musl
* x86/64 musl
* x86/64 glibc
* armvirt/64 musl
The size of the images stays more or less the same for MIPS BE and
aarch64. I haven't tested other architectures.
With GCC 11 I got these sizes for lantiq/xrx200:
7,219,848 openwrt-lantiq-xrx200-tplink_tdw8970-initramfs-kernel.bin
7,472,208 openwrt-lantiq-xrx200-tplink_tdw8970-squashfs-sysupgrade.bin
With GCC 12 I got these sizes for lantiq/xrx200:
7,217,355 openwrt-lantiq-xrx200-tplink_tdw8970-initramfs-kernel.bin
7,406,674 openwrt-lantiq-xrx200-tplink_tdw8970-squashfs-sysupgrade.bin
The sysupgrade image is probably padded. The initramfs image is 0.03% smaller.
With GCC 11 I got these sizes for armvirt/64:

ChangeLog:
Version 2.16.01
_This is a documentation update release only._
(*) Fix the creation of the table of contents in the HTML version of
the documentation.
Version 2.16
(*) Support for the `rdf' format has been discontinued and all the
RDOFF utilities has been removed.
(*) The `--reproducible' option now leaves the filename field in the
COFF object format blank. This was always rather useless since
it is only 18 characters long; as such debug formats have to
carry their own filename information anyway.
(*) Fix handling of MASM-syntax reserved memory (e.g. `dw ?') when
used in structure definitions.
(*) The preprocessor now supports functions, which can be less
verbose and more convenient than the equivalent code implemented
using directives. See section 4.4.
(*) Fix the handling of `%00' in the preprocessor.
(*) Fix incorrect handling of path names affecting error messages,
dependency generation, and debug format output.
(*) Support for the RDOFF output format and the RDOFF tools have
been removed. The RDOFF tools had already been broken since at
least NASM 2.14. For flat code the ELF output format
recommended; for segmented code the `obj' (OMF) output format.
(*) New facility: preprocessor functions. Preprocessor functions,
which are expanded similarly to single-line macros, can greatly
simplify code that in the past would have required a lengthy
list of directives and intermediate macros. See section 4.4.
(*) Single-line macros can now declare parameters (using a `&&'
prefix) that creates a quoted string, but does _not_ requote an
already quoted string. See section 4.2.1.
(*) Instruction table updated per public information available as of
November 2022.
(*) All warnings in the preprocessor have now been assigned warning
classes. See appendix A.
(*) Fix the invalid use of `RELA'-type relocations instead of `REL'-
type relocations when generating DWARF debug information for the
`elf32' output format.
(*) Fix the handling `at' in `istruc' when the structure contains
local labels. See section 5.9.2.
(*) When assembling with `--reproducible', don't encode the filename
in the COFF header for the `coff', `win32' or `win64' output
formats. The COFF header only has space for an 18-character
filename, which makes this field rather useless in the first
place. Debug output data, if enabled, is not affected.
(*) Fix incorrect size calculation when using MASM syntax for non-
byte reservations (e.g. `dw ?'.)
(*) Allow forcing an instruction in 64-bit mode to have a (possibly
redundant) REX prefix, using the syntax `{rex}' as a prefix.
(*) Add a `{vex}' prefix to enforce VEX (AVX) encoding of an
instruction, either using the 2- or 3-byte VEX prefixes.
(*) The `CPU' directive has been augmented to allow control of
generation of VEX (AVX) versus EVEX (AVX-512) instruction
formats, see section 7.11.
(*) Some recent instructions that previously have been only
available using EVEX encodings are now also encodable using VEX
(AVX) encodings. For backwards compatibility these encodings are
not enabled by default, but can be generated either via an
explicit `{vex}' prefix or by specifying either `CPU LATEVEX' or
`CPU NOEVEX'; see section 7.11.
(*) Document the already existing `%unimacro' directive. See section
4.5.12.
(*) Fix a code range generation bug in the DWARF debug format
(incorrect information in the `DW_AT_high_pc' field) for the ELF
output formats. This bug happened to cancel out with a bug in
older versions of the GNU binutils linker, but breaks with other
linkers and updated or other linkers that expect the spec to be
followed.
(*) Fix segment symbols with addends, e.g. `jmp _TEXT+10h:0' in
output formats that support segment relocations, e.g. the `obj'
format.
(*) Fix various crashes and hangs on invalid input.

When building with an external toolcahin with musl also include
./include/fortify by default. This is also done when we build with the
internal toolchain using musl libc.
Without this extra include the fortify source feature is not working
when using an external musl toolchain. All binaries were compiled
without fortify source when an external musl toolchain was used. All
binaries release done by the OpenWrt project use the internal toolcahin
where fortify source is working.

Every minor version bump of a major version will result in a huge patch
diff because of the moving of all the patches from version e.g. 11.2.0 to
11.3.0. This commit only use the major version for the patch folders to

improve the reviewing of the smaller version bump patches and help to see

libstdcxx-dual-abi needs to be enabled to actually support C++11 ABI.
Enable the config flag to also permit support of .NET 6 development on
OpenWrt.

GCC 12.1 is out. Add support for it.
Deleted (upstreamed):
011-v12-configure-define-TARGET_LIBC_GNUSTACK-on-musl.patch
931-libffi-fix-MIPS-softfloat-build-issue.patch
Deleted (unneeded?)
970-macos_arm64-building-fix.patch
Other patches manually rebased due to C++ conversion and consequent file name
changing (.c to .cc).

dwarves is a set of tools that use the debugging information inserted in
ELF binaries by compilers such as GCC. Utilities in the dwarves suite
include pahole, which can be used to find alignment holes in structs and
classes, and also extracts other information such as CPU cacheline
alignment, helping pack those structures to achieve more cache hits.
These tools are also used to encode and read the BTF type information
format used with the bpf syscall, making this a Linux build dependency
when using kernel BTF information.

Changes:
new features:
- qsort_r function (POSIX-future)
- pthread_getname_np extension function
- hard float on SPE FPU for powerpc-sf
- SEEK_DATA and SEEK_HOLE exposed in unistd.h (Linux extensions)
compatibility:
- free now preserves errno (POSIX-future requirement)
- setjmp is declared explicitly with returns_twice for non-GCC compilers
- macro version of isascii is no longer defined for C++
- dynamic linker now tolerates zero-length LOAD segments
- epoll_[p]wait is now a cancellation point
- pwd/grp functions no longer fail on systems without AF_UNIX support
- POSIX TZ parsing is stricter to allow more names to fallback to files
- NULL is now defined as nullptr when used in C++11 or later
- gettext now accepts null pointer as argument
bugs fixed:
- old regression in wcwidth of Hangul combining (vowel/final) letters
- duplocale used wrong malloc when malloc was replaced (1.2.2 regression)
- fmaf rounded wrong on archs without FE_TOWARDZERO (all softfloat archs)
- popen didn't honor requirement not to leak other popen pipe fds to child
- aligned_alloc and variants crashed on allocation failure
- dl_iterate_phdr reported incorrect module TLS pointers
- mishandling of some inputs in acoshf and expm1f and functions using them
- potentially wrong-sign zero in cproj functions at infinity
- multiple bugs in legacy function cuserid
- minor posix_spawn file actions API conformance issues
- pthread_setname_np fd leak
- out-of-bound read in zoneinfo handling with distant-past times
- out-of-tree builds lacked generated debug cfi for x86 asm
arch-specific bugs fixed:
- powerpc (32-bit) struct shmid_ds layout was wrong for some fields
- time64 struct layout was wrong in sound ioctl fallback (32-bit archs)
In addition it contains the following improvements:
* protect stack canary from leak via read-as-string by zeroing second byte
* fix excessively slow TLS performance on some mips models
