Subject: [PATCH] autotools: check for sched_getcpu()

sched_getcpu() is glibc-only, so not portable. Mac OS X
does not have it, and has no obvious replacement function.

This commit will allow future code to test for the existence
of this function, to provide fallbacks instead of making
compilation fail.
