Subject: use generic blas and lapack
The upstream project typically uses either the AOCL BLIS library or the
Netlib BLAS library as the reference implementation in the test suite on
Linux. However, the OpenBLAS library is used by upstream on Windows. It
would be nice to use OpenBLAS on Debian for performance reasons (as the
test suite is heavily CPU-bound), however, the Netlib implementation
seems to be more reliable for achieving a full suite of passing tests.
