* config/linux/proc.h: New.

	* config/linux/proc.c: Include "proc.h".  Do not include <sched.h>.
	(gomp_cpuset_popcount): Rename from cpuset_popcount.  No more static.
	(gomp_init_num_threads): Update call to cpuset_popcount.
	(get_num_procs): Ditto.
	* config/linux/affinity.c (gomp_init_affinity): Call
	gomp_cpuset_popcount.
