I'm wrestling with the idea of what makes an arch "valid", considering the list supported here is only the subset of archs that llvm knows about. E.g., is m68k an invalid Mach-O file? And so on. I readily concede this is the most pedantic of concerns.

I think maybe `Supported` is more appropriate.  PPC should be a known valid arch as IIRC even though it is not currently supported by the interface.
