It seems to me that ??= gets confused because the variable name needs 
expanding. If you change the ${DEFAULTTUNE} reference to core2 in 
PACKAGE_EXTRA_ARCHS_tune-${DEFAULTTUNE} ??= "${TARGET_ARCH}" it all works. I 
don't know if that indicates a BitBake bug or whether we should try to work 
around it.
