Nixpkgs: Numpy-1.17.{2-4} segfaults tests when built with openblas

[stites]

Describe the bug
I am getting a segfault in the check phase of numpy-1.17.4 with openblas, specifically when running test_ufunc.py on the following commit

{
  "url": "https://github.com/NixOS/nixpkgs.git",
  "rev": "20c33be286abd80e41537609843fc50f14a15560",
  "date": "2019-12-12T12:18:55-05:00",
  "sha256": "1j8yw337hdafisdzj1c2s847ag2gcic9633gvsicyiipxiyi4a1h",
  "fetchSubmodules": false
}

The same thing happens when building numpy-1.17.2 from my unstable nixpkgs branch. **To Reproduce** You can use the above pin (created Dec 12th, 2019) and simply drop into a nix-shell with something like

nix-shell -p '(python3.withPackages (ps: [(ps.numpy.override({ blas = openblas;}))]))'

**Expected behavior** Nix-shell compiles numpy **Results**

The standard numpy in nixpkgs is already build against openblas. However, it is built against openblasCompat, which uses the 32 bit integer interface. openblas uses the 64 bit integer interface. This is common problem with Fortran libraries. Both, the program linking the library and the library itself, must be built with the same convention (see ILP64 vs LP64)
