Sorry but we can't do this. One reason for some of the recent changes
was to move the handling of this to the metadata and out of bitbake.
We've therefore now got:

include conf/multiconfig/${BB_CURRENT_MC}.conf

in bitbake.conf and the system looks for the file that way. The user is
free to add other files in other paths and bitbake doesn't know/care
about the directory layout.

If we really want to make this error, we'd need to add an empty
conf/multiconfig/default.conf and then change this to a require instead
of an include. Bitbake's standard error messages would then kick in.

Cheers,

Richard
