   +          better be, as we are directly calling an ECOFF backend function.  */
   +       if (strncmp (bfd_get_target (abfd), "ecoff", 5))
   + 	einfo ("%F%B: all input objects must be ECOFF for --embedded-relocs\n");

Just check for bfd_target_ecoff_flavour here.  Don't make assumptions
about the target name.
