x86: fix race to build arch/x86/efi/relocs-dummy.o
With $(TARGET).efi depending on efi/relocs-dummy.o, arch/x86/Makefile will attempt to build that object. This may result in a dependency file being generated that has relocs-dummy.o depending on efi/relocs-dummy.S. Then, when arch/x86/efi/Makefile tries to build relocs-dummy.o, well efi/relocs-dummy.S doesn't exist. Have only one makefile responsible for building relocs-dummy.o.
