kbuild: make KBUILD_NOCMDDEP=1 handle empty built-in.o
Based on a patch by Rabin Vincent.
Fix building with KBUILD_NOCMDDEP=1, which currently does not work
because it does not build built-in.o with no dependencies:
LD fs/notify/built-in.o
ld: cannot find fs/notify/dnotify/built-in.o: No such file or directory
ld: cannot find fs/notify/inotify/built-in.o: No such file or directory
ld: cannot find fs/notify/fanotify/built-in.o: No such file or directory
