- Update to glibc 2.21 release.
* A new semaphore algorithm has been implemented in generic C code for all
machines
* Added support for TSX lock elision of pthread mutexes on powerpc32,
powerpc64 and powerpc64le
* Optimized strcpy, stpcpy, strchrnul and strrchr implementations for
AArch64
* i386 memcpy functions optimized with SSE2 unaligned load/store
* New locales: tu_IN, bh_IN, raj_IN, ce_RU
* The obsolete sigvec function has been removed
- Patches from upstream removed
* ifunc-x86-slow-sse4.patch
* pthread-mutex-trylock-elision.patch
- o-tmpfile.patch: Fix value of O_TMPFILE for architectures with
non-default O_DIRECTORY (BZ #17912)
