As of b892099902402c1179d7183b6ac97ca517faae7a we can no longer do sanity check on the host distribution on systems that don't have lsb_release installed (not unlikely for minimal/headless systems on distros that bring in a large number of dependencies when installing the LSB package.) We need to have a fallback in meta/lib/oe/lsb.py in case lsb_release isn't available.
