Kevin, you were the last person to work on the FRV target (far as I
can tell); do you know anything about this?

Ulrich, there's a third option, but I don't know if it's practical.
Can we somehow specialize the remote target based on the architecture?
It's not the first time I've thought it would be useful.  But we
already have the target adjusting the architecture and adding
something in the other direction might be awkward.
