commit: http://git.uclibc.org/uClibc/commit/?id=3a3ad3dfc10876b3648369f22df8fc06661ddef0
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master

The argument names used in the prctl wrapper collide with the internal
variable names in syscall wrapper macros on some architecture. This
currently breaks xtensa. grep for '\b_a[0-9]' indicates that metag and
microblaze might also be affected.

Prefix argument names with '_prctl' to avoid collision.
