Recognizing/translating cpu names

On linux/SPARC the platform string returned from config.guess is
"sparc64-unknown-linux-gnu", but the build system doesn't currently
recognize "sparc64" as a valid cpu name. I'd like some feedback on how
to address this. I can see two ways:
1. Add it to the list of recognized cpu names and map it to the "normal"
sparc values, something like:
2. Massage/translate the string in config.guess to return something
better (e.g. sparcv9-unknown-linux-gnu)
I notice that we do the latter type of translation for some
platforms/strings, but it's not clear to me what the pros and cons are
of the respective approaches. Please advise.
