To throw in a tangential non-x86 perspective, I would prefer that
there be no -M default at all. For ARM at any rate there is no
machine which is inherently preferable or better than any other;
the current default is integratorcp simply because it happened to
be the first one implemented, and this tends to lead to user errors
where people don't realise that not passing in a -M option results
in their getting an ancient and barely maintained model...
