Lubomír Sedlář 454363fba8 Allow specifying empty variants 
The variants.xml file can list a variant with is_empty="true" and no
groups. If such variant is found, not package gathering will be run for
it, and no repos will be created.

This only makes sense for a variant that will have some other
deliverables like live media or images.
