I'd like to understand this better as I don't like the idea of depending
on an arbitrary file that isn't part of the kernel build system to build
modules.

It seems to me that these modules should be able to DEPEND on something
provided by the kernel recipes, rather than checking the contents of a
file stuck in the build tree.
