I can confirm this works, thanks!

I need

arch/powerpc/kernel/Makefile: 
CFLAGS_early_32.o += $(DISABLE_LATENT_ENTROPY_PLUGIN)
arch/powerpc/lib/Makefile:
CFLAGS_feature-fixups.o += $(DISABLE_LATENT_ENTROPY_PLUGIN)

to make it going on my G4 with GCC_PLUGIN_LATENT_ENTROPY=y. Modifying
setup_32.o is not needed.
