#37415: py27-numpy: cannot import numpy when built with atlas

Comment (by vince@…):
BTW, Atlas builds quickly with gccXX because it has, for GCC only, a set
of precomputed figures optimizing the various parameters of the different
kernels. In the case of Clang, no such set is available, so Atlas goes
through the whole process of testing each combination of parameters to
find the best one. Takes several hours (usually ca. 4 to 6)
But now that Clang correctly compiles Atlas, it is probable that Clint
Whaley, the senior developer, will include precomputed figures for Clang
in a future revision.
