It's not a new warning, I've observe it for several recent major kernel releases already.

I do not build with CONFIG_COMPILE_TEST.

I've also realised I see this warning with -O3 only. I know this is unsupported, so feel free to ignore me, but I do -O3 builds for finding out possible loose ends in the code, and this is the only place where it breaks.
