Ah, I see, I've always let gcc call ld/libtool/etc so I've never
touched them.

Yup, that did it. Now it builds cleanly. I think I'll submit my
libhid0.info now. One last question, I don't quite get the rules for
when a package would be called libhid0 vs. libhid. I figure that
since this library is version 0.2.16, the package should be called
libhid0. Is that correct?
