I'm appending a close to trivial config.abi which handles the most basic
choice between 32-bit and 64-bit. I'm not familiar at all with the more
obscure cases, so I haven't tried adding them to the case construction
(they should clearly be added early in the sequence of patterns).
If you think this is going in the right direction, I can check it in
(and I'd suggest the name config.abi, to be somewhat consistent with the
naming of other autoconf helper scripts).
