There is no rule to build those built-in.o targets below third directory level. Even current kbuild system could achieve this with rule "%/", while this not only builds built-in targes but also lib target, extra target and module objects. This patch adds the "%/built-in.o" rule so that each built-in.o in the kernel tree could be the build target, which looks more consistent for the kbuild system.
