IIRC you're hitting a linker bug. Let me quote from arch/x86/Makefile:
$(obj)/stage0.o $(obj)/stage0.init $(obj)/stage0-prefixed.o: $(STAGE0_OBJ)
        $(Q)# We need to be careful. If stage0.o gets bigger than
        $(Q)# 0x4000 - 0x100, we will end up with a 4 gig file.
        $(Q)# I wonder if that behavior is on purpose.
