Mark Mentovai f614332197 include/prereq-build.mk: macOS cross build improvements
This updates prereq-build.mk to find a suitable realpath utility, and
adds another place to look for a suitable getopt utility.

realpath has been used most notably by scripts/ipkg-build since
commit bb95be9265 ("scripts,ipkg-build: use realpath for pkg_dir")
and there are assorted other uses of it during a build.
It is ordinarily provided by GNU coreutils. This adds a SetupHostCommand
to locate it either under its own name or under grealpath, the name that
it will be available as under MacPorts or Homebrew, which use
--program-prefix=g.

Similarly, update the SetupHostCommand for getopt to be able to locate a
util-linux getopt at the default path used by MacPorts, in the same
fashion that
commit cc16f5d73e ("build: try to find getopt in macOS homebrew's standard location")'
did for Homebrew. As there is no standard alternative --program-prefix
for util-linux utilities in the way that GNU packages often use a "g"
prefix, this path-based approach is required in case a non-util-linux
getopt (such as one provided by an OS) shadows the util-linux getopt
in the PATH.

Christian 'Ansuel' Marangi ab1f3a8706 prereq-build: add additional git detection
With some OS (Guix) the git submodule command is wrapped in
a script. Current logic parse the git submodule script directly.
If it's wrapped the prereq check wrongly fails while 'git submodule
--recursive' is actually available.
Add an additional check that try to directly use the 'git submodule'
command to check if the prereq is satisfied.

Andre Heider 60af8d7533 prereq-build: require python3-distutils
Debian and Ubuntu ship a python3-minimal package which does not include
the distutils module. This is not supported by upstream and can be
considered a broken python distribution.

In practice, many scripts depend on said module, and this is a reoccuring
pain point for building various OpenWrt packages.

Require and check for said module, enough time has been wasted on this.

Bas Mevissen f68c9474ac Extend checks on build prerequisites for building OpenWRT core
OpenWRT requires a number of Perl modules to be installed. It wasn't checking on all of them.
This patch adds checks for Perl FindBin, File::Copy, File::Compare and Thread::Queue modules.

Failing to install these, will have the build break at some point. By adding these to the
prereq-build.mk script, they are checked on forehand.

Tested on a Fedora 33 and 34 (beta) that was freshly installed. Fedora appears to
break up Perl modules into small packages that need to be installed for the build to succeed.

Kevin Darbyshire-Bryant 8c8496435a build: add GNU install to prerequisites
The recent removal of usbutils from core and replacement by hwdata in
packages has exposed hwdata's requirement for certain GNU options on
'install' (-T)  Other packages (sqm-scripts) have openwrt specific
makefile sections to avoid GNU options but I suspect this is going to
get harder in the future.

Add GNU install as a prerequisite and link into
$STAGING_DIR/host/etc/bin as per similar GNU utils

This resolves an issue building under MacOS which would otherwise use a
non-GNU options aware version of 'install'

Andre Heider 7379f8bd3e build: prereq: drop support for Python 3.5
The final Python 3.5 release was 3.5.10 in September 2020 [0].
This release series is now End-of-Life (EOL).

The only LTS distribution that still only ships Python 3.5 is Ubuntu 16.04,
which will be EOL in April 2021 [1].

The meson build system bumped their python requirement to 3.6 for the 0.57.0
release. This patch ensures that OpenWrt can update meson while still
relying on the host python.

Kevin Darbyshire-Bryant a5100a0bd1 build: simplify gnu-getopt search
getopt is the only command where /usr/local/bin is specified explicitly.
All other commands are assumed to exist in the PATH in one form or
another.  Remove this exception and require gnugetopt/getopt to be in
the user's PATH.

In the case of macos Homebrew, getopt is 'keg only' hence not linked
into /usr/local/bin whilst other commands are linked and likely found by
virtue of /usr/local/bin being in PATH.

Since 2019 Homebrew is very reluctant to install links that have
potential to override default OS behaviour, eg: following instructions
on our current 'how to build on macos' wiki page:

$ brew ln gnu-getopt --force
Warning: Refusing to link macOS-provided software: gnu-getopt
If you need to have gnu-getopt first in your PATH run:
  echo 'export PATH="/usr/local/opt/gnu-getopt/bin:$PATH"' >> ~/.zshrc

A better option for macos is to link getopt as 'gnugetopt' in
/usr/local/bin, thus the build system will find 'gnugetopt' but other
applications looking for just 'getopt' will find the original macos
binary.

Ultimately it makes sense that 'GNU' dependencies are placed in
/usr/local/bin and /usr/local/bin is included in the user's PATH.

Kevin Darbyshire-Bryant 4d87963381 build: add xargs as prerequisite
Build system needs an 'xargs' that supports '-r' which darwin doesn't.
Homebrew installs a 'gxargs' with the findutils package so look for
'gxargs' as well as 'xargs'

This is a bit of a 'fun' corner case anyway. xargs is only required by
the build if 'CONFIG_AUTOREMOVE' is set and after the build system has
built 'tools/findutils' we have a fully working xargs for host anyway.
Until that time we have to rely on the host's xargs implementation.

Petr Štetiar 19938c8de7 build: switch to Python 3
This patch switches Python used in buildroot to Python 3 as Python 2.x
series is going to be EOL relatively soon[1].

 "Being the last of the Python 2.x series, 2.7 will have an extended
  period of maintenance. Specifically, 2.7 will receive bugfix support
  until January 1, 2020. After the last release, 2.7 will receive no
  support."

It seems like Python 3 is going to be needed in order to support Meson
build system which has gained some traction recently.

Build tested on following targets:

 ath79/generic
 imx6/generic
 ipq40xx/generic
 lantiq/xway
 layerscape/armv7 (broken)
 layerscape/armv8_32b (broken)
 layerscape/armv8_64b (broken)
 mvebu/cortexa72
 ramips/mt7621
 ramips/mt7620
 sunxi/cortexa7
 x86/64

Layerscape targets are unfortunately left broken as their ls-rcw
firmware package uses Python 2 and converting it to Python 3 would take
more then reasoanble amount of time (I've tried to fix it already) and
would be better fixed by someone who can even run test it.

Run tested on ath79 (Archer C7 v5), ipq40xx (nbg6617) and x86_64 (QEMU
and apu2).

Busybox time supports the GNU time '-f' syntax used by the build time
logging implemented in ff6e62b288, however the prerequisite check added
only works with GNU time installed as `time` or `gtime`.

As busybox is a multicall binary, the name of the symlink setup by
SetupHostCommand also must be changed from `gtime` to `time` to fix the
value of argv[0]. This causes a number of shells (including bash) to use
their builtin impelementation of time, so the sole invocation has been
changed to use `env time` to use the value found on the $PATH.

Hauke Mehrtens d6d3db0543 build: Improve GCC version detection
This now makes sure that the beginning of the version number gets checked
and "4.4.5" will not match was a supported version.
GCC 8 and GCC 9 are now marked as supported, but we probably have to fix
some problems for them.

Justin Kilpatrick 8ee2d3f718 build: accept gcc/g++ without minor version
Build dependency: Please install the GNU C Compiler (gcc) 4.8 or later cc
  -dumpversion | grep -E '(4\.[8-9]|5\.[0-9]|6\.[0-9]|7\.[0-9])'
Build dependency: Please install the GNU C++ Compiler (g++) 4.8 or later
  g++ -dumpversion | grep -E '(4\.[8-9]|5\.[0-9]|6\.[0-9]|7\.[0-9])'

Prerequisite check failed. Use FORCE=1 to override.

On my Fedora 26 machine gcc and g++ -dumpversion returns a whole number
'7' failing the regex introduced in commit:

b78de6207f

This change makes minor versions optional in the build dependency regex
for gcc and g++ whenever any minor version would be accepted and the
whole number version is sufficient as a dependency check. For versions
4.* a minor version is still required.

Daniel Engberg b78de6207f toolchain: Test for supported versions of GCC
Only test for supported versions of GCC
The version bump requirement for GCC is because gdb doesn't build with older
versions.
