I don't see anything in config.guess that would create such a name (config.guess tries to avoid testing $CC as much as possible, and testing the ABI used by $CC would be necessary to distinguish x32), so while people can use such a triplet to change the default ABI for the target, I wouldn't expect it necessarily to be used for the host. -- Joseph S.
