Auto-test for different BLAS implementation during python installation

[dweindl]

One of the main issues people seem to be having with AMICI installation are BLAS-related. Would be good to add a test to compile a tiny test program to try different default paths / cblas-compatible libraries and automatically detect a working configuration (cblas, openblas, atlas, mkl, ...). The advanced user should still be able to override that.

I would guess that other packages faced the same problem and we might not have to reinvent the wheel there (e.g. numpy). Even better to change to CMake-based build (#721). Or 'simply' provide wheels #423.

Good guess for CentOS7 would be BLAS_LIBS="-L/usr/lib64/atlas/ -lsatlas"

Might also be helpful to check for an existing installation of https://anaconda.org/anaconda/openblas and use headers/libraries from there.
