On GNU/Hurd we not only need $(common-objpfx) in LD_LIBRARY_PATH when loading
dynamic objects, but also $(common-objpfx)/mach and $(common-objpfx)/hurd. This
adds an ld-library-path variable to be used as LD_LIBRARY_PATH basis in
Makefiles, and a sysdep-ld-library-path variable for sysdeps to add some
more paths, here mach/ and hurd/.

I don't think sysdep-ld-library-path should include the leading
separator.  Instead, ld-library-path can use
$(addprefix :,$(sysdep-ld-library-path)).

Andreas.
