Comment (by vbraun):
The new version d33e9114156d8373fa61f957b379e029 changes the "fast" 64-bit
archdef to `P4E64SSE3`.
It turns out that there are no 64-bit generic archdefs, which might have
been one reason for why ATLAS was slow to compile. The SPKG uses the
existing 32-bit archdefs or the 64-bit one that I made. On x86 the spkg
should produce a working ATLAS library within 10-30 mins, and only go
through the tuning process if either
* CPU throttling is disabled (`scaling_governor=performance`, needs
root), or
* SAGE_ATLAS_ARCH is explicitly set to something different from "base" /
"fast".
