Use BLAS instead of ATLAS by default.
I used to recommend the use of ATLAS over the standard fortran BLAS.
Unfortunately for some time we are not packaging ATLAS anymore, and very
recently the source code of GotoBLAS has been made available for
research purposes. GotoBLAS is said to be faster than ATLAS and the
shared library is exchangeable with the standard BLAS. Curiously the
standard BLAS is known to beat both GotoBLAS and ATLAS when the problems
are not too complex, so I expect it's better for beginners.
I am hereto recommending the use of shared blas by default but leaving a
WITH_ATLAS knob in case someone doesn't have access to GotoBLAS and
wants to try to squeeze some more performance.
