toolchain/musl: bump to version 1.1.24

1.1.24 release notes

new features:
- GLOB_TILDE extension to glob
- non-stub catgets localization API, using netbsd binary catalog format
- posix_spawn file actions for [f]chdir (extension, pending future standard)
- secure_getenv function (extension)
- copy_file_range syscall wrapper (Linux extension)
- header-level support for new linux features in 5.2

performance:
- new fast path for lrint (generic C version) on 32-bit archs

major internal changes:
- functions involving time are overhauled to be time64-ready in 32-bit archs
- x32 uses the new time64 code paths to replace nasty hacks in syscall glue

compatibility & conformance:
- support for powerpc[64] unaligned relocation types
- powerpc[64] and sh sys/user.h no longer clash with kernel asm/ptrace.h
- select no longer modifies timeout on failure (or at all)
- mips64 stat results are no longer limited to 32-bit time range
- optreset (BSD extension) now has a public declaration
- support for clang inconsistencies in wchar_t type vs some 32-bit archs
- mips r6 syscall asm no longer has invalid lo/hi register clobbers
- vestigial asm declarations of __tls_get_new are removed (broke some tooling)
- riscv64 mcontext_t mismatch glibc's member naming is corrected

bugs fixed:
- glob failed to match broken symlinks consistently
- invalid use of interposed calloc to allocate initial TLS
- various dlsym symbol resolution logic errors
- semctl with SEM_STAT_ANY didn't work
- pthread_create with explicit scheduling was subject to priority inversion
- pthread_create failure path had data race for thread count
- timer_create with SIGEV_THREAD notification had data race getting timer id
- wide printf family failed to support l modifier for float formats

arch-specific bugs fixed:
- x87 floating point stack imbalance in math asm (i386-only CVE-2019-14697)
- x32 clock_adjtime, getrusage, wait3, wait4 produced junk (struct mismatches)
- lseek broken on x32 and mipsn32 with large file offsets
- riscv64 atomics weren't compiler barriers
- riscv64 atomics had broken asm constraints (missing earlyclobber flag)
- arm clone() was broken when compiled as thumb if start function returned
- mipsr6 setjmp/longjmp did not preserve fpu register state correctly

Refreshed all patches.
Removed upstreamed.

-Subject: [PATCH] make relocation time symbol lookup and dlsym consistent
-
-Using common code path for all symbol lookups fixes three dlsym issues:
-
-- st_shndx of STT_TLS symbols were not checked and thus an undefined
-  tls symbol reference could be incorrectly treated as a definition
-  (the sysv hash lookup returns undefined symbols, gnu does not, so should
-  be rare in practice).
-
-- symbol binding was not checked so a hidden symbol may be returned
-  (in principle STB_LOCAL symbols may appear in the dynamic symbol table
-  for hidden symbols, but linkers most likely don't produce it).
-
-- mips specific behaviour was not applied (ARCH_SYM_REJECT_UND) so
-  undefined symbols may be returned on mips.
-
-always_inline is used to avoid relocation performance regression, the
-code generation for find_sym should not be affected.

-Subject: fix x87 stack imbalance in corner cases of i386 math asm
-
-commit 31c5fb80b9eae86f801be4f46025bc6532a554c5 introduced underflow
-code paths for the i386 math asm, along with checks on the fpu status
-word to skip the underflow-generation instructions if the underflow
-flag was already raised. unfortunately, at least one such path, in
-log1p, returned with 2 items on the x87 stack rather than just 1 item
-for the return value. this is a violation of the ABI's calling
-convention, and could cause subsequent floating point code to produce
-NANs due to x87 stack overflow. if floating point results are used in
-flow control, this can lead to runaway wrong code execution.
-
-rather than reviewing each "underflow already raised" code path for
-correctness, remove them all. they're likely slower than just
-performing the underflow code unconditionally, and significantly more
-complex.
-
-all of this code should be ripped out and replaced by C source files
-with inline asm. doing so would preclude this kind of error by having
-the compiler perform all x87 stack register allocation and stack
-manipulation, and would produce comparable or better code. however
-such a change is a much larger project.
