IIRC that didn't exist outside cycle then.

Neither do I. It is not an option that I regularly use. Maybe it was a
workaround for the problems where later -Xr (rlink-path) was added for. IOW
cross-shared linking wasn't so easy then.

Anyway, I'll update and play with it in the coming times. I had already
planned to spend some time on the buildfaq, and this is good training.
