Comment (by jdemeyer):
As far as I know, nothing in Sage ''directly'' uses BLAS, it is only used
through external libraries (linbox, numpy, ...)
So it's a mystery why some extensions in `src/module_list.py` list the
BLAS libraries without any other library. And indeed, on my Linux box,
Sage still works after the following change:

Perhaps those libraries are needed for some reason (I know Linux in
particular is very flexible with defining libraries) but it's something to
be investigated...
