Hmm, I originally suggested adding the flags to ALL_CFLAGS:

   $(ALL_HOST_FRONTEND_OBJS): ALL_CFLAGS += -DIN_GCC_FRONTEND

but then changed my mind and switched to adding them to .c.o.

I suppose you have to add $(CFLAGS-$@) to ALL_CFLAGS. :-)

Yes, likely the makefile fragments haven't been included when you do the 
$(eval).
