Well, the right thing to do would be to turn arch to ev6, and then
restore it to whatever it was previously; with this patch, it remains
turned on for the rest of the file and could potentially hide errors.
However, I don't think that's possible with gas. So given this
deficiency, I don't think there's a better way.
