Hokay! So I wrote a patch that gets me through the compile:
https://src.fedoraproject.org/rpms/condor/blob/master/f/libdl.patch

This doesn't seem to be in the idiom of HTCondor, but I don't know
enough about CMake to know how to make it not an ugly hack. If you
want, I'll open a ticket with the patch attached and you can do what
you want with it. This will probably be necessary as your supported
platforms move to glibc 2.29.
