lang/dmd build failure

I think we had this one before.

cp /usr/lib/libc.so.97.* /tmp/pobj/dmd-2.104.0/dmd-bootstrap/openbsd/bin64/ # XXX
cp: /usr/lib/libc.so.97.*: No such file or directory

I don't have a good suggestion. Maybe this should be mimicking the
| sort -rV | head -1 dance from /etc/rc to be a bit more robust.
