This is not an undocemented behavior. First it is documented that later
options should override the earlier ones. Second this is an expected change.
Third you should have reported this to Apple first since you are using their
compiler and their build numbers prove it. Thrid the reason for this change
was to allow -mcpu=G4 -mno-altivec.
Fourth it is not incompatible at all as -mcpu=G4 -mpowerpc-gpopt works as
expected as -mpowerpc-gpopt adds to -mcpu=G4.
