My hurd cross-build doesn't have that reference.

That indicates the symbol is undefined.  Look at the corresponding lines in
the readelf -s output.  There should be no undefined symbols in ld.so,
so this looks like a bug in how it's getting built.  -z defs would have
caught this, and I've added that to the link for ld.so.  We'll have to look
into what is breaking the build on the Hurd.  Likely wrong objects being
brought in or the rtld-* compilations not happening right.
