[PATCH v2 16/26] kbuild: generate a list of objects in vmlinux
From: Masahiro Yamada
Date: Sun May 01 2022 - 04:44:45 EST
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.

Changes in v2:
- Move '> .vmlinux.objs' to the outside of the loop (Nicolas)
- Clean up .vmlinux.objs explicitly
