For x86 Hurd, GCC has been specifying »-dynamic-linker /lib/ld.so« in
LINK_SPEC since forever (1995, or earlier), and Debian glibc has had the
following since forever (2002, or earlier):

    ifeq ($(DEB_HOST_GNU_SYSTEM),gnu)
    # Why doesn't the glibc makefile install this?
           ln -sf ld.so.1 $(tmpdir)/$@/lib/ld.so
    endif

Roland, do you have any recollection of this?  Assuming that /lib/ld.so.1
is the "official" name, I suppose GCC should be changed, and then Debian
could drop the symbolic link after a transition period (full archive
rebuilt, etc.).
