Can't you grep some preprocessor symbol instead of introducing another tool into config.guess with 'file'? There are a few similar examples in the script already.
You can simply check whether the __LP64__ macro is defined. This is done already in config.guess for hppa-hp-hpux, you can certainly use similar logic.
