This wouldn't work as "core2" is PACKAGE_ARCH and PACKAGE_ARCH is not in
OVERRIDES. I did briefly discuss this over jabber and you could do:

FULL_OPTIMIZATION_i586= "-fexpensive-optimizations -frename-registers -O2 -ggdb -feliminate-unused-debug-types"

since TARGET_ARCH (i586) is in OVERRIDES but this would then affect
machines like qemux86 and I decided we didn't want to do that at this
point in the release cycle.

Cheers,
