Linking MKL is always fun. See [1]. Note that I used lapack_libs and
mkl_libs in site.cfg, in contrast to what is mentioned in [2,3].

I did a serial build, but you just need to replace mkl_sequential
-> mkl_intel_thread.

Your icc doesn't seem to use "-O2 -g -openmp -avx", but the
distutils default "-m64 -fPIC -shared".
