What I mean is ATLAS is unaware of the T2+ processors, whereas it has
information about the UltraSPARC III+ processors. That's why it takes so long to
build on 't2'
ATLAS seems to be a bit problematic in Sage, with many of these issues
outstanding a long time.
* I have this problem.

* MartinX is finding it is not building on his i5-750 processor processor.
(we need to create a trac ticket for that. Does MartinX have an account?)
* There is no tuning information on the T2+ processors on 't2.math'

* On 't2,math' ATLAS dumps core in one of the tuning routines, so we have a hack
which returns a reasonable (unoptimised) value from the tuning routine
http://trac.sagemath.org/sage_trac/ticket/6276
* ATLAS ignore CC variable and dumps core if one tries to build with SunStudio
