It may be empty but our packaging criteria say we always generate a dbg
package since they can be part of dependency chains and we're
interested in the dependencies.

I appreciate in this case, the libc-headers are a corner case at the
end of the chains so you could argue this one can be skipped for
packaging but the system does assume all -dbg packages exist so I'd
prefer to leave this alone, unless its part of a bigger picture rethink
about -dbg packages.

Cheers,

Richard
