Numpy and Scipy build on Mac imported into the main branch

We were developing the build of Numpy and Scipy on Mac in a parallel thread
and things seems to be working relatively nice now. There were only two
problems:

1) GCC still has some random building issues on Mac.

2) ATLAS shared libraries can't be built on Mac (so we used OpenBLAS to
   build Numpy and Scipy on both Mac and GNU/Linux).

But for now, none of these problems are critical. So, we can progress in
one branch.

There were only very minor conflicts in the merge.
