Getting some warnings from the clearcase fetcher (they're not using it, but bitbake still parses the code). The warnings are related to python3.8 (and later) checking whether the "is" comparison keyword is used on literals (where == should be used instead). This has been fixed upstream: [https://github.com/openembedded/bitbake/commit/1fab03f6e10eaa13b8a89ce0b2f9fe8ce5157189]
