    bitbake.conf: add VOLATILE_LOG_DIR variable
    
    The default value is "yes" which results in the /var/log being a link
    pointing to /var/volatile/log which is on tmpfs.
    
    Setting valid boolean false value ('no', 'n', 'false', 'f', '0') would make
    /var/log to be a directory on persistent storage.
