m68k in -next builds fine for me, and did for a while. I have not seen a build
failure there. There must be a context commit causing this failure, or what
is (or was) in -next differs from what is in mainline.

Yes, that is correct. But that doesn't mean that it would be a good idea
to retire COMPILE_TEST.
