This patch consolidates the sched_getcpu implementations across all
arches (except tile, which requires its own). This patch removes
the powerpc, x86_64 and x32 specific files and change the default
linux one to use INLINE_VSYSCALL where possible (for ports that
implements it).
* sysdeps/unix/sysv/linux/sched_getcpu.c: New file.
* sysdeps/unix/sysv/linux/x86_64/sched_getcpu.S: New file.
* sysdeps/unix/sysv/linux/Versions: Export sched_getcpu for
GLIBC_2.6.
