Make march/target-cpu print a note with the list of valid values for ARM
When rejecting a march= or target-cpu command line parameter,
the message is quite lacking. This patch adds a note that prints
all possible values for the current target, if the target supports it.
This adds support for the ARM/AArch64 targets (more to come!).
