Well, but does it actually fit all the variations of -mabi=/-march= that
we implement? I have no access to that tool, so I can't tell...

Well, I'd rather warn about dangerous constructs.
Finding out the difference to historic GNU binutils behaviour may be
tough as for the corner cases the sets will be different depending on the
version chosen. If you're careful enough with that choice, you may
actually end up with disjoint sets... Trivial cases, like "la $2, 0" are
likely to have always worked as expected. ;-)
