I think this is what I was trying to say, as well.  (except that the
way of specifying it would simply be -march=<isa or CPU>.)

I _do_ think that it's important to support -mtune, but that's another
kettle of fish (and not particularly important for binutils to
anything with except maybe ignore, or use to be a bit more careful
when implementing e.g. 'move').
