Comment (by kencu):

 gcc-10 would not have made any difference, so it likely was that ppc7400
 thing again, as I first thought, that was corrected when you adjusted the
 test.

 I wonder why someone would ever want to use CPU_SUBTYPE_POWERPC_7400
 instead of CPU_SUBTYPE_POWERPC_ALL anyway?... well, they must have had
 some reason.
