Well, that does not make sense for all ports, for example rs6000.
POWER and PowerPC have defined architectures that do not change from
processor to processor. One wants to specify a CPU to set both
architecture and tuning parameters. Saying -march=604 is incorrect and
-march=powerpc is not specific enough.
