Sorry I missed it, but the subject line was a bit misleading.  The
patch is fine.  However, the PPC already has a way of selecting the
default CPU (and thus scheduling etc) with a configure option and
config.gcc.  Did you look at that mechanism before implementing this
one?

And I predict that at some point in the future, there will be a thread
about how all those defines in config.gcc are cluttering up the
script, and why can't we put them all in target-specific headers?
