I don't mean a hack to glibc*.bb, but rather changing base.bbclass (and
anything else) to not blow up if OVERRIDES contains duplicates.  I think
it's possible to add a python function that does it, but it would have
to be 'slow' since the fast method is to throw everything into a dict
and then return the list of keys.  So perhaps it's best to just say
libc-<foo> for an additional per-libc override.
