It contains as usual some cleanups and support for new stuff.
UCLIBC_HAS_LFS got removed.
The new release includes experimental support for microblaze
NPTL/TLS and Nios2 MMU systems (static only, no ld.so/NPTL/TLS).
The test suite got removed and is a separate project now.
That ensures that all tests are compiled with the full gcc and not
with some intermediate compiler.
