Did you do the buildworld with -DNO_CLEAN? Do you see ">>> Deleting
stale dependencies..." in the log, and if so can you collect the 10 or
so lines after that?

Removing /usr/obj and trying again will fix it, but I would really
like to get to the bottom of this and fix it in the tree. If you're
going to remove /usr/obj perhaps you can snapshot your VM and try some
experiments later?
