This patch lets the user specify -mcpu=G[345] or -mtune=G[345]. G3 is a synonym for 750, G4 for 7450 and G5 for 970. Users of Apple's Darwin compiler can already do this.Could also update config.gcc so that you can configure with --with-cpu=?
Tested by compiling simple programs with the various flags.
OK to commit?

Thanks, Andrew Pinski
