Mixing with/without hyperref is problematic, for the target
an anchor is needed that is exported in the .aux file, that
is done by hyperref. In the other file the link is also done
by hyperref.

With hyperref \label writes the anchor name in the .aux file
that can then be read by other programs/packages in other
files, such as xr-hyper.
