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.
