So I really shouldn't be tripping over this anymore, but can we somehow
this mess?

- at least add it to the normal build system and kconfig deps instead
of stashing it away so that things like buildbot can build it?
- at least allow building it (under COMPILE_TEST) if needed even when
pmem.ko and friends are built in the kernel?
