modpost: show warning if any of symbol dump files is missing
If modpost fails to load a symbol dump file, it cannot check unresolved symbols, hence module dependency will not be added. Nor CRCs can be added. Currently, external module builds check only $(objtree)/Module.symvers, but it should check files specified by KBUILD_EXTRA_SYMBOLS as well. Move the warning message from the top Makefile to scripts/Makefile.modpost and print the warning if any dump file is missing. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
