Doesn't this mean that the available licenses will be calculated once 
per recipe? Or isn't it a problem since the time will not be spent 
during recipe parsing, but rather during task execution where no one 
will notice if the create-spdx task for all recipes takes a little 
longer?

That said, if I remember correctly from the last time I looked at this 
function, it should be possible to rewrite it to not rely on 
available_licenses() without any real loss in functionality.
