I think it's probably best to just drop the entire parenthetical

precise documentation on what needs to be done on ARM.

In fact, it might be better to just rewrite the whole section based on a
theoretical machine that has two ISAs, one which can support
floating-point and one which can't.  You then get back to essentially
the same text as we had originally but anonymised and future proofed.
Yes, this is a good idea. Or, carrying it even farther, you could make the whole thing hypothetical, like "Suppose a target supports flags @option{-mfoo} and @option{-mbar} that are mutually exclusive...."
