kbuild: do not try to build content of initramfs
When a file supplied via CONFIG_INITRAMFS pointed to a file for which kbuild had a rule to compile it (foo.c => foo.o) then kbuild would compile the file before adding the file to the initramfs. Teach make that files included in initramfs shall not be updated by adding an 'empty command'. (See "Using Empty Commands" in info make). Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
