Is that really true?  I thought e500v2 was an actual core and the
equivalent architecture was Power v2.03 or something.

Since we do ship tune-ppce500.inc in oe-core, I think it makes sense to
also include the overrides necessary to make compilation work with SPE
enabled.  It doesn't seem unreasonable that users would expect that the
recipes in oe-core would work with a configuration that comes as
standard.

However, adding overrides for e500v2 specifically does seem like a bad
plan since we will then end up having to duplicate the thing for every
other non-altivec configuration.  Can you come up with some override
that will apply to all SPE configurations, or failing that a patch for
the configure script that will disable the altivec assembler if it
notices that ${CC} is configured for SPE?
