I don't see any "gcc -m" type of dependency generation pass happening
in this relatively simple Make system.

It happens with -MD, all the deps are stored in files like mm/.init-mm.o.cmd
and sucked into the build.

You are thinking of kbuild. This is not kbuild. There are no such artifacts
being generated.

Oh. Really? That's horrible.

Well, yes, it's not a perfect build system down here in selftests/. Are you saying
that it is worth upgrading? I'm open to suggestions and ideas for improvements,
and at the moment, I have the miniature build system here mostly loaded into my
head. So for a brief shining moment I can probably understand it well enough to
work on it. :)
