[PATCH v3 05/15] kbuild: generate a list of objects in vmlinux

[Masahiro Yamada <masahiroy@kernel.org>]

A *.mod file lists the member objects of a module, but vmlinux does
not have such a file to list out all the member objects.

Generate this list to allow modpost to know all the member objects.
