Subject: Fix link error on Linux/musl.
X-Git-Tag: v0.2.11^2~4^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f7eb81a84676bce20fcf1df3462639d0bc1b28f0;p=platform%2Fupstream%2Fopenblas.git

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.)
