[OE-core] gcc 4.8 - ICE

[Mark Hatle]

Ran into an internal compiler failure w/ the new gcc 4.8 today.

I suspect the ppce500v2 tuning hasn't been used much, but it appears to trigger 
the failure case.

Should I enter a bug for this issue in the YP bugzilla?  I can also attempt to 
file a bug w/ gnu this weekend or early next week.
