More assembly than C according to github's count. I'm used to building
the full version of openblas including their optimized implementations
of lapack routines, which bring in libgfortran. So nevermind.

test program with your build to use more than 2 cores (I have 4 + HT)
by setting the OPENBLAS_NUM_THREADS environment variable.
