It looks like I messed up spectacularly when backporting that commit; those files should not have been added. I must have had those lying around from a rebase or similar. I'll spin a patch for v4.9.y to drop the bits I added erroneously. It is somewhat concerning that no-one spotted that (myself included) when the v4.9.y backport was originally made. :/ Thanks, Mark.
