Different ATLAS versions have different routines so the architectural

If you don't want top performance then you can always set
SAGE_ATLAS_ARCH=fast or SAGE_ATLAS_ARCH=base when compiling Sage, this
will use some generic settings but will build much faster.
I have tried all of these tricks and still couldn't get atlas, g2fx to
build. Both of them remain stuck at some tuning stage.
On the git version, with make -j2, givaro fails to build because it
seems to get built before gmp. This is completely reproducible every
time I run a "make distclean; make -j2" cycle.
I looked at my base system packages (gentoo linux) and the only major
thing that has changed since the last time I could build sage
(sage-5.11-beta3) is the kernel which I upgraded from 3.7.10 to 3.9.11.
For some reason, I can't get any version of sage to build now.
