egrep -r '\-Wa' arch/ppc
arch/ppc/boot/simple/Makefile:extra-aflags-$(CONFIG_REDWOOD_4)  := -Wa,-m405
arch/ppc/Makefile:cpu-as-$(CONFIG_PPC64BRIDGE)  += -Wa,-mppc64bridge
arch/ppc/Makefile:cpu-as-$(CONFIG_4xx)          += -Wa,-m405
arch/ppc/Makefile:cpu-as-$(CONFIG_6xx)          += -Wa,-maltivec
arch/ppc/Makefile:cpu-as-$(CONFIG_POWER4)               += -Wa,-maltivec
arch/ppc/Makefile:cpu-as-$(CONFIG_E500)         += -Wa,-me500

So I get an invalid instruction error.
