I don't think so. The separate directory was necessary before, since
ATLAS shipped its own modified copy of lapack with an identical library
name (liblapack) as lapack.

However, ATLAS still has different flavors for different CPUs (e.g.
3dnow, sse, sse2, sse3 etc). I'm not sure if this can be easily handled
with alternatives.
