Subject: Numpy: Replace ATLAS and liblapack with openblas (that has blas and
 lapack).

Was previously with ATLAS [Automatically Tuned Linear Algebra Software].
This takes ages and has little to no performance benefit over openblas+lapack.
And if you need this performance, you should really built it against your own hardware.
