[PATCH] Fix PR testsuite/1504

Turns out there is an inconsistency between platforms in the error
message one gets when reading from a bit of memory that isn't

memory_error (int status, CORE_ADDR memaddr)
  struct ui_file *tmp_stream = mem_fileopen ();
  make_cleanup_ui_file_delete (tmp_stream);

  if (status == EIO)
      /* Actually, address between memaddr and memaddr + len
         was out of bounds. */
      fprintf_unfiltered (tmp_stream, "Cannot access memory at address ");
      print_address_numeric (memaddr, 1, tmp_stream);
      fprintf_filtered (tmp_stream, "Error accessing memory address ");
      print_address_numeric (memaddr, 1, tmp_stream);
      fprintf_filtered (tmp_stream, ": %s.",
                       safe_strerror (status));

  error_stream (tmp_stream);

I wonder whether we should try to unify this.  In the meantime, this
patch fixes the fall-out in the testsuite.
