The only reason I mentioned it is the "new" default behavior of the
compiler is appropriate for only a very small subset of the cores,
and your solution only addresses some of the ones affected.
In the past, the default behavior was fine for all but your
special case :-)
My concern wasn't specifically for which options I wanted, but
rather for the mechanism to set all of them now that it appears
we need to do that.

OK, but we still need some kind of indication from the configuration
process. It seems to me it would be easier (and more logical) to
have the default behavior work like it has in the past, and use the
special options for the POWER4, which we already know in
