If a flag is added, I would prefer that we keep the flag naming
consistent between all the tools when possible. AVR GCC uses the flag
-mmcu=<device>, where <device> can be a named AVR device in lowercase or
"architecture" like "avr6".

Upon review, I'd be ok with '-m arch' too.

I think that it would be good to add this switch as it would help with
testing different devices/architectures in the future. These differenct
architectures typically select different instruction sets. It would be
good to know if a specific architecture is broken wrt the gcc regression
tests.
