I suggest that we unmask the appropriate ARCH flags in
profiles/arch/*/use.mask, add ../base to profiles/arch/*/parent, and
create profiles/arch/base/use.mask to mask all of the existing ARCH
flags. This will serve to mask all but the appropriate ARCH flags
for all of the 2008.0 profiles. Does this seem reasonable?
