Subject: [PATCH v5 09/10] kbuild: vmlinux.unstripped should always depend on .vmlinux.export.o

Since .vmlinux.export.c is used to add generated by modpost modaliases
for builtin modules the .vmlinux.export.o is no longer optional and
should always be created. The generation of this file is not dependent
on CONFIG_MODULES.
