Hi Alexandros, Richard,

It's not that we want to mimic GCC, but we also don't want to create new names that will never be used by binutils (which we still rely on).

Moreover, this change is more in sync to the LLVM philosophy that we should map the most common representation of a core, not the bare minimum. If the default configuration of R5s and M4s is to have VFP, then we shall represent it that way and let the minority of users disable them via flags.

LGTM, thanks!
