musl 1.1.10 released

musl 1.1.10 released

[Rich Felker]

This release fixes regressions introduced as part of the dynamic
linker bootstrap overhaul in musl 1.1.9, and adds several new features
and improvements. Internal cleanup and optimizations have been made to
the locale system. A fail-safe/allocation-free locale_t object for the
C locale is now available via newlocale(), and the iconv_open function
now supports "" and "CHAR" as aliases for the native (UTF-8) encoding.
A new crt start file, rcrt1.o, is provided for producing static-linked
position independent executables (PIE). Minor PIE-related
arch-specific bugs, and a bug in the ungetc and ungetwc stdio
functions which caused them to fail on files in EOF status, have also
been fixed.

There's relatively nasty regression in uselocale() breaking most X
applications (due to some libraries).

See patch at:

Uhg, this kind of thing is exactly why I've been wishing we had tests
for locale functions. I tested it minimally by hand but didn't think
to try passing (locale_t)0. I'll probably make a fix release with this
patch applied.

Regression test for just this one issue is attached. We should still
have some big locale functionality tests, though...
