config.guess/config.sub improvements

["Lassi A. Tuura" <Lassi dot Tuura at cern dot ch>]

[-- I already sent this to gcc2@cygnus.com, but then came to think
    that perhaps I should send it to this list, too.  Is that true
    in general, or is it sufficient to send small patches like this
    to gcc2 only? --]

Here is a patch for config.guess (from gcc-2.7.2.3) to correctly
determine processor types on HP's PA-RISC, plus small additions for
PowerPC LynxOS and cygwin32.  For the cygwin32 entry I am not sure what
is the desired format; please check it.

The PA-RISC table for 800-series is rather complicated and I am not sure
if I got it right; it is correct for the entries I had in my
/opt/langtools/lib/sched.models.  In particular, there are lots of
models missing from that file (probably still unassigned), so the
heuristics below might be incorrect for future models.  If my
sched.models does not include all past models, then it might be
incorrect for older computers, too.

Cheers,

        * config.guess: more accurate determination of HP PA-RISC
        processor types for 9000/[678]?? series machines, add support for
        PowerPC on LynxOS and for Windows NT on CYGWIN32.

        * config.sub: ditto.
