I've backpatched a few other changes too.

I find it extremely useful to run CI on backbranches before
batckpatching. Enough so that I've thought about proposing backpatching CI all
the way.

I don't think it's that much work to fix this kind of thing in the
backbranches. We don't need to backpatch new tasks or such. Just enough stuff
to keep e.g. the base image the same - otherwise we end up running CI on
unsupported distros, which doesn't help anybody.

I think we should apply the fix in <= 15 - IMO it's a correct compiler
warning, what we do right now is wrong.
