lib/libc/arch/powerpc/sys: cerror.S sigprocmask.S tfork_thread.S
Log message:
Make __cerror() use the per-thread errno location if r2 isn't zero. This way
libpthread no longer has to override it which means that we can use a local
call and can avoid setting up r30 as a _GLOBAL_OFFSET_TABLE_ pointer, which
is hard the way the powerpc ABI works.
For now we continue to provide __cerror as a weak symbol, but ___cerror is
now protected and internal calls within libc now use ___cerror instead of
__cerror.
