Use __builtin_popcount in __sched_cpucount [BZ #21696]
posix/sched_cpucount.c assumes that size of __cpu_mask == size of long, which is incorrect for x32. This patch uses __builtin_popcount, which is availabe in GCC 4.9, in posix/sched_cpucount.c. Tested on i686, x86-64 and x32 with multi-arch disabled. [BZ #21696] * posix/sched_cpucount.c: Don't include <limits.h>. (__sched_cpucount): Use __builtin_popcount.
