Makefile: convert makefiles to Kbuild style and delete grep switch
We have converted all makefiles needed to build $(LIBS). Until this commit we used to grep switch so that U-Boot style and Kbuild style makefiles coexist. But we do not need any more. Goint forward, use always Kbuild style Makefile when adding a new Makefile Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
