Using a custom Xtensa configuration requires an overlay that provides
that configuration; not providing an overlay is like using the default
configuration, BR2_xtensa_fsf, so there would be no point in that case
in requesting a custom configuraiton.
Make providing an overlay mandatory for custom configurations.
