Hmm? I haven't seen anything from the bots, but the existing behavior was broken as well, and arguably worse - -mtune shouldn't set the architecture :)

If you file a bug I'll try to get it where -mcpu will set arch and tune if -march isn't passed and -mtune aren't passed.

The arm port is just broken if it tries anything else.
