    bitbake: tinfoil: ensure log lines get printed when tasks fail
    
    If a task fails during build_targets(), we need to print out the log
    lines as knotty does or the user will be missing information about the
    failure.
    
    (This should get some deeper refactoring, but now isn't the time for
    that.)
