No. We can expand multi-lists at ANY OTHER POINT than O_OBJS. That's ok.
It's only O_OBJS that has any ordering issues.

And we just shouldn't use OX_OBJS at all, as that breaks ordering _and_
can be done equally well with MIX_OBJS instead.

We can add a comment to the Makefile. That's trivial.

What's not trivial, and what I WANT DONE is to make sure that _when_
somebody wants to maintain link ordering, he can do so in an easy and
obvious way. Not with Yet Another Hack.
