Title: BUG: fix atlas/blas detection

ATLAS' detection in numpy is not necessarily reliable and does not always work (e.g. see Gentoo's patches [1,2]).

Removing the `('NO_ATLAS_INFO', 1) in blas_info.get('define_macros', []))` part enables sklearn to be properly compiled with ATLAS support on Gentoo & Gentoo Prefix (i.e. Gentoo in non-root user space).

Is this line just copied from numpy's setup? Does it have a purpose for sklearn? If not, then I believe we should merge this PR.

Of course I am open to discussion ;-)
