I would assume it's rustc that's broken.  It gives a diagnostic that is
not at all related to the thing you claimed to have removed for testing.

What the heck is this good for, where config dependency would be useful?

It's the basic setup of the Debian Linux package.  linux-kbuild is for
the build arch, aka the system the build runs on; linux-headers-* is for
the host arch, aka the system the kernel is built for.

So, either "macros" is static and unchanging, then we can just build it
and don't care.  Or it is dynamic, then it needs to be built next to the
external module and not be shipped at all.
