arch/xtensa: custom configuration requires an overlay

Browse Source 
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.

    xtensa-buildroot-linux-uclibc/bin/ld: ldso/ldso/ld-uClibc_so.a(ldso.oS): compiled for a big endian system and target is little endian
