[git commit] stubs: unified from future
Bernhard Reutner-Fischer

Mon Mar 26 09:25:33 UTC 2012
commit: http://git.uclibc.org/uClibc/commit/?id=899a2731262c4321f44a0faecf4134f6b6eacc3d
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master
Future branch extends stubs with ret_enosys_stub.
Resolve conflicts, and use superset of future and current master.
Adjust posix_fadvise* accordingly.
Upon future merge, pick this master version as the final state.
