Not sure if the arm people want to review this or would rather I review it... Let's give the arm folks a couple days to comment, if no objections, Ok. A point of warning, eventually, you'll discover that when a compiler defaults to the argument you want to skip, that you'll needs slightly more power to skip them. darwin ran into this with things like -m64, and eventually had to do something like lp64. configure options like --with-cpu=arm9 are the sort that can change the default.
