MCORE2 seems to get one oddball compiler flag (-march=core2):
cflags-$(CONFIG_MCORE2) += \ $(call cc-option,-march=core2,$(call cc-option,- mtune=generic))
It would be interesting to see if replacing the above "$(call" with:
$(call cc-option,-mtune=generic)
makes the problem go away the same way as changing the .config option.
Definitely.

But double-checking that "-march=core2" case is definitely worth looking into. Especially since there are clear indications that it's gcc version-dependent anyway. Alexander?
Yes, the change suggested by Dave makes the problem go away.
