Merge patch series "kbuild: Fixes for fallout from recent modules.builtin.modinfo series"

This is a series to address some problems that were exposed by the
recent modules.builtin.modinfo series that landed in commit c7d3dd9163
("Merge patch series "Add generated modalias to
modules.builtin.modinfo"").

The third patch is not directly related to the aforementioned series, as
the warning it fixes happens prior to the series but commit 8d18ef04f9
("s390: vmlinux.lds.S: Reorder sections") from the series creates
conflicts in this area, so I included it here.
