toolchain/musl: update to 1.2.4

Browse Source 
Release notes:

new features:
- large dns record lookups via tcp fallback
- new getaddrinfo EAI_NODATA result to distinguish NODATA/NxDomain
- support for new RELR compressed format for relative relocations
- sysconf keys for querying signal stack size requirements
- real vfork on riscv64

performance:
- mallocng no longer uses MADV_FREE (high performance cost, little gain)
- vdso clock_gettime is supported once again on 32-bit arm

compatibility:
- gethostbyname family now distinguishes NO_DATA from HOST_NOT_FOUND
- res_send now works with caller-provided edns0 queries
- arpa/nameser.h RR types list is now up-to-date
- previously-missing POSIX confstr keys have been added
- mntent interfaces now accept missing fields
- alt signal stack, if any, is now used for internal signals
- the LFS64 macros are no longer exposed without _LARGEFILE64_SOURCE
- memmem (POSIX-future) is now exposed in default feature profile
- pthread_atfork now admits calls from an application-provided malloc
- debugger tracking of shared libraries now works on MIPS PIE binaries
- sendmsg now supports up to SCM_MAX_FD fds in SCM_RIGHTS messages

bugs fixed:
- gethostbyname[2]_r wrongly returned nonzero (error) on negative result
- parallel v4/v6 address queries could fail on query id collisions
- spurious getaddrinfo/AI_ADDRCONFIG failures due to errno clobbering
- dns search domains ending in dot (including lone dot) broke lookups
- ipv6 servers in resolv.conf broke lookups on systems with v6 disabled
- systems with bindv6only failed to query both v4 and v6 nameservers
- res_mkquery mishandled consecutive final dots in name
- res_send could malfunction for very small answer buffer sizes
- resolver dns backend accepted answers with wrong (A vs AAAA) RR type
- getservbyport_r returned junk or ENOENT (vs ERANGE) on buffer size errors
- dns result parsing of malformed responses could process uninitialized data
- freopen didn't reset stream orientation (byte/wide) & encoding rule
- fwprintf didn't print most fields on open_wmemstream FILEs
- wide printf %lc ignored field width
- wide printf erroneously processed %n after encoding errors
- use of wide printf %9$ argument slot overflowed undersized buffer
- swprintf malfunctioned on nul character in output
- strverscmp ordered digit sequences vs nondigits incorrectly
- timer_create/SIGEV_THREAD failure leaked the thread
- semaphores were subject to missed-wake under certain usage patterns
- several possible rare deadlocks with lock handling at thread exit
- several possible rare deadlocks with aio and multithreaded fork
- dynamic linker relro processing was broken on archs w/variable pagesize
- async cancellation could run cancellation handlers in invalid context
- pthread_detach was wrongly a cancellation point in rare race code path
- use-after-close/double-close errors in mq_notify error paths
- mq_notify event thread wrongly ran with signals unmasked
- wcs{,n}cmp, wmemcmp returned wrong results when difference overflowed
- accept4, pipe2, and dup3 handled unknown flags wrong in fallback cases
- CPU_SETSIZE macro had wrong unit
- select fallback for pre-time64 kernels truncated timeout (vs clamping)

arch-specific bugs fixed:
- x32 new socketcalls took fallback path due to pointer sign extension
- x32 wait4 didn't fill rusage structure (time64 regression)
- x32 semtimedop mismatched timespec ABI with kernel (time64 regression)
- sigaction signal mask was bogus on or1k, microblaze, mips, and riscv
- powerpc-sf longjmp asm clobbered value argument
- or1k poll function passed timeout to syscall in wrong form

Removed upstreamed:
- 800-mips_pie_debug.patch
Manually rebased:
- 600-nftw-support-common-gnu-extension.patch

Fix DT_DEBUG handling on MIPS in musl libc.
With this change gdb will load the symbol files for shared libraries on MIPS too.
