[PATCH] kbuild: get lib-y objects back to static library

[Masahiro Yamada <masahiroy@kernel.org>]

Revert the following two commits:

 - 7273ad2b08f8 ("kbuild: link lib-y objects to vmlinux forcibly when CONFIG_MODULES=y")
 - 7f2084fa55e6 ("[kbuild] handle exports in lib-y objects reliably")

Now, lib-y is back to static library again, and the link order is
consistent w/wo CONFIG_MODULES.

Since commit ddb5cdbafaaa ("kbuild: generate KSYMTAB entries by
modpost"), .vmlinux.export.c contains references to exported symbols.
If a symbol in a lib-y object is exported, that object is always linked
even without any explicit user in vmlinux.
