[Bug target/24913] undocumented new CPU upgrade by -mpowerpc-gpopt overrides user-selected -mcpu= setting

Of course, G4 and G5 are marketing names for *FreeScale* 74xx and IBM ppc970xx
cpus respectively. These are listed under the values that can be given to -mcpu
et al, but I can't find them in the list of cpus given under -mpowerpc-gpopt et
al.

I give up. Are you contradicting what you just said earlier? In that case the
phrase I cited in #6 is wrong!

Gcc has so many convenience/t options that warn the programmer for doing unwise
things. Why not add a warning (or error) when requesting impossible cpu
features, or ones that are not available on the current host cpu?
