musl - an implementation of the standard library for Linux-based systems

the file-level crt_arch.h asm fragments generally make direct (non-PLT) calls from _start to _start_c, which is only valid when there is a local, non-interposable definition for _start_c. generally, the linker is expected to know that local definitions in a main executable (as opposed to shared library) output are non-interposable, making this work, but historically there have been linker bugs in this area, and microblaze is reportedly still broken, flagging the relocation for the call as a textrel. the equivalent _dlstart_c, called from the same crt_arch.h asm fragments, has always used hidden visibility without problem, and semantically it should be hidden, so make it hidden. this ensures the direct call is always valid regardless of whether the linker properly special-cases main executable output. |

musl libc
musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.
The 1.1 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.
For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
