    insane: only check ${S} exists if we had sources to fetch
    
    Only check that ${S} actually exists if there was something in ${SRC_URI} to
    fetch, the argument being that if SRC_URI is empty the the recipe won't be using
    ${S} at all.
    
    In general recipes that have no sources can remove the unpack task, but
    expecting all recipes to do this relatively advanced operation isn't realistic.
