This includes detecting ATLAS, as well as looking for static versions of LAPACK/BLAS that can be linked into a shared object (-fPIC). The only such library found on Ubuntu systems seems to be OpenBLAS (but only with -lm and -lpthread dynamically linked, since -lm -lpthread are not compiled with -fPIC).
