Only copying files, and not the recipes, to an overlay, does not work.

It would be quite nice, but I understand the complexities if every FILE 
has to be
search for in all the collections.

The current behaviour is, as I understand:

If no PREFERED_VERSION, select highest version of a package, else 
PREFERED_VERSION.
Iterate through collections by priority, select the collection that 
provides the "package-version".
Use that collection as the base directory for accessing FILES.
