Currently, the top Makefile includes all of scripts/Makefile.<feature> even if the associated CONFIG option is disabled. Do not include unneeded Makefiles in order to slightly optimize the parse stage. Include $(include-y), and ignore $(include-). Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
