Do our processor names always correspond to real processor names?  It was my understanding that there is no such thing as a "Cortex-M4F" processor: http://sourceware.org/ml/binutils/2010-09/msg00184.html  So, GCC & binutils definitely don't have "cortex-m4f".

FWIW, if we don't, then I think we should strive to always use actual processor names.
