In Kbuild, if_changed and friends must have FORCE as a prerequisite.
Hence, $(filter-out FORCE,$^) or $(filter-out $(PHONY),$^) is a common
pattern to get the names of all the prerequisites except phony targets.
Add real-prereqs as a shorthand.
Note:
We cannot replace $(filter %.o,$^) in cmd_link_multi-m because $^ may
include auto-generated dependencies from the .*.cmd file when a single
object module is changed into a multi object module. For details,
see commit 69ea912fda74 ("kbuild: remove unneeded link_multi_deps").
I added a comment to avoid accidental breakage.

If you want to apply this series cleanly, please apply the following first:
https://patchwork.kernel.org/patch/10761625/
https://patchwork.kernel.org/patch/10767193/
The conflicts are not significant.
You can use 'git am -C1' if you want to apply this series
directly to Linus tree.
