I understand that you have to work with 4.1, but the first step is
still to look at HEAD and see what other people have already fixed.
For instance:

  /* If not cross-compiling, search well-known system locations.  */
  if (*cross_compile == '0')
    {
#ifndef OS2
      add_prefix (&exec_prefixes, standard_exec_prefix_1, "BINUTILS",
                  PREFIX_PRIORITY_LAST, 2, 0);
      add_prefix (&exec_prefixes, standard_exec_prefix_2, "BINUTILS",
                  PREFIX_PRIORITY_LAST, 2, 0);
#endif
      add_prefix (&startfile_prefixes, standard_exec_prefix_2, "BINUTILS",
                  PREFIX_PRIORITY_LAST, 1, 0);
    }

So no, a cross toolchain will not refer to /usr.
