-----------------------------+----------------------------
Since we want the choice of blas/lapack to be configurable by `.pc` files
we need to have `numpy` and `scipy` obey to `pkg-config`.
This is complicated by the fact that `numpy/scipy`'s build system will
look for
1) mkl
2) openblas
3) threaded atlas 3.10.x (tatlas.so)
4) single thread atlas 3.10.x (satlas.so)
5) threaded atlas (any versions)
6) single thread atlas (any versions)
7) accelerate on OS X
8) blas/lapack configuration provided by the user
9) blas/lapack source provided by the user
In that order from (1) to (9). Note that the user's wishes are ignored
unless everything else fails. Getting `numpy/scipy` to obey `pkg-config`
may therefore require patching.
