What does this message mean, and why do I get it with most of the
shared libraries I try to build?

[SNIP]

I've built the world statically from to-day's sup, and got this message
with the tools built from that run, so it's still going on.

At this point, I don't really care if it's fixed soon (since I'm just
going to recompile everything statically anyway), but I'm really curious
as to what's going on here.
