1) Why not just -mcpu=supersparc.  -mv8 is deprecated in favor of
   -mcpu= syntax anyway.

2) We have CPUFLAGS make variable for -mcpu= and its ilk.  Potential
   bonus of using it is that it's applied to assembler files as well
   (unlike CFLAGS &co).  I think at least some ports (arm most likely)
   already use that option to provide customized asm stuff.
