toolchain: musl: Update to version 1.2.3 (#9241) 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 Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Acked-by: Rui Salvaterra <rsalvaterra@gmail.com> Tested-by: Rui Salvaterra <rsalvaterra@gmail.com> Tested-by: Koen Vandeputte <koen.vandeputte@ncentric.com> Co-authored-by: Hauke Mehrtens <hauke@hauke-m.de>
