Howard Su ff1da01476 USE NPROCESSOR_CONF instaed of NPORCESSOR_ONLN 
to determine the number of CPU. In ARM platform,
online CPU will increasing when there is more workload.
while configure cpu is the max number of CPU.

Isaac Dunham f7eb81a846 Fix link error on Linux/musl. 
get_nprocs() is a GNU convenience function equivalent to POSIX2008
sysconf(_SC_NPROCESSORS_ONLN); the latter should be available in unistd.h
on any current *nix. (OS X supports this call since 10.5, and FreeBSD
currently supports it. But this commit does not change FreeBSD or OS X
versions.)
