Since BLAS (and LAPACK) have an essentially well-defined ABI, anything dynamically ELF-linked doesn't need specific support. You can just LD_PRELOAD, say, OpenBLAS or blis+libflame (as in AOCL) to use them. You can also make a trivial libblas.so.3 shim to put on LD_LIBRARY_PATH. (Debian has a heavyweight approach to linear algebra alternatives, with separate builds of the whole library.)
