config ISA here is already unselectable, and nothing ever does "select
ISA" (only in some other architectures), so is there much point in this?

I'm not even sure why this exists at all.

But anyway, adding a dependency to a always-false symbol doesn't make it
less always-false :-)

Certainly will be nice to get rid of this cruft for architectures that
don't have it.
