I was surprised to find that the sandybridge (Xenon E5-2690) would not compile for
CPUTYPE?=bonnell (this is intel atom N450) as the N450 is a lot (2010) older.

But the haswell compiles for CPUTYPE?=bonnell fine.

This is what made me wonder if there's some kind of fault with the
Xenon E5-2690. Or maybe it just can't use CPUTYPE?= properly? Does its use
require any special capability of the host chip?

If I don't put any CPUTYPE?= in poudriere's make.conf on the Xenon, 
everything compiles as expected without error. Maybe I should just do this ;)

*** although I'm going to continue compiling for btver1 on the haswell as the
resulting system feels more responsive.

thanks,
