Testing with --target=FOO

Which ones?  Back when we only had an arm model to work with, we
were expedient and hard-coded tests to use that.  But now, with
many more ports in-house, those old tests should generally be
made cpu-independent, or replicated in multiple cpu-dependent
copies, as appropriate.

Maybe.

Nah.

:  + Build the arm7t model unconditionally, regardless of the target.
:    Only the cpu is required as far as I can tell.

Can you provide more details on why some canonical cpu is required
for what are presumably non-cpu tests?


or #4:

+  Change the test suite.
