According to gcc.info for PPC

`-mtune=CPU_TYPE'
     Set the instruction scheduling parameters for machine type
     CPU_TYPE, but do not set the architecture type, register usage, or
     choice of mnemonics, as `-mcpu=CPU_TYPE' would.

-mcpu=670 might provide better performance.  Don't know if it's
a big or tiny or no benefit.
