Subject: musl 1.1.12 released

This release features arch-independent support for FDPIC, an ABI
variant that allows text segment sharing without MMU by relaxing the
usual ELF requirement that data reside at a fixed displacement
relative to code, and arch-specific support for FDPIC on SH2. CFI
(call frame information) generation support has also been added for
x86_64 asm, improving debugging backtraces, especially when a program
is stopped during a syscall.

Several toolchain and application compatibility improvements have been
made, most notably in regards to the new byte-based C locale, where
nl_langinfo(CODESET) now returns "ASCII" rather than
"UTF-8-CODE-UNITS"; the latter broke many applications which assumed
the returned string would be a meaningful, well-known character
encoding name.

Bugs fixed include deadlock at exit when stdin or stdout was closed, a
missing memory barrier in pthread_join, and minor corner case bugs in
various interfaces.
