--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This is a binutils testsuite issue.

```
proc default_ld_link { ld target objects } {
    global host_triplet
    global exec_output

    set flags ""
    if [is_endian_output_format $objects] then {
        set flags [big_or_little_endian]
    }

    remote_file host delete $target
    set exec_output [run_host_cmd "$ld" "$flags -o $target $objects"]
    set exec_output [prune_warnings $exec_output]

    # We don't care if we get a warning about a non-existent start
    # symbol, since the default linker script might use ENTRY.
    regsub -all "(^|\n)(\[^\n\]*: warning: cannot find entry
symbol\[^\n\]*\n?)" $exec_output "\\1" exec_output

    return [string match "" $exec_output]
}
```

prune_warnings  is not pruning the warning for `warning: using serial
compilation of N LTRANS jobs`.
