I don't think it is my job to find such a target. Rather, it is up to
you to prove that no target will ever need that.

Anyway, I don't think this kind of approach to our argument is
productive. I suggest that we instead concentrate on finding an
alternative machinery to compute TARGET_HAS_HARDWARE_WATCHPOINTS at
configure time.

How about this: for a cross-compiled build or for remote targets, add
a switch to the configure script, say --without-hw-watchpoints, that
will set TARGET_HAS_HARDWARE_WATCHPOINTS so as to disable hardware
watchpoint support; for native and non-cross builds, add an autoconf
test that will do that automatically?
