This is a follow-up to the series[0] that adds Kbuild warning if an
object is linked into several modules (including vmlinux) in order
to prevent hidden side effects from appearing.
The original series, as well as this one, was inspired by the recent
issue[1] with the ZSTD modules on a platform which has such sets of
vmlinux cflags and module cflags so that objects built with those
two even refuse to link with each other.
The final goal is to forbid linking one object several times
entirely.

Patches 1-7 and 10-11 was runtime-tested by me. Pathes 8-9 and 12-18
are compile-time tested only (compile, link, modpost), so I
encourage the maintainers to review them carefully. At least the
last one, for cpsw, most likely has issues :D
Masahiro's patches are taken from his WIP tree[2], with the two last
finished by me.

This mostly is a monotonic work, all scores go to Masahiro and
Alexey :P
