Never mind! I figured it out. I poked around in the links.def file and found the field definitions. I replaced the following code in the link.html file:

href="<%db_cgi_url%>/jump.cgi?ID=<%ID%>"

with this:

href="<%URL%>"

I crossed my fingers and rebuild the links, and hey presto! The links were generated with the site URL!

Now that I've spent my evening banging my head on this, I'll go read a book for the rest of the night and start trading links again tomorrow!
