Well for target specific flags, the backend maintainer(s) have to do the
conversion. At some point, I hope to do the power/powerpc backend, but it
isn't high on the priority list.
For the optimization flags, in theory it should work for all targets right now.
I'm sure there are various bugs, including some that have already been
reported.
