These are now installed in /usr/lib/autoconf ($acdatadir) as of 2.10-2.

Should that perhaps go in /usr/doc/examples instead?

Hmm. I suppose it might be interesting to have config.guess identify
the "vendor", though many of the debian packages that use configure
already specify it directly. I don't know if anything really should
need to conditionalize on the vendor (frankly, anything that needs the
config.guess output is probably insufficiently autoconfiscated anyway :-)
but if someone will recommend a way to identify the vendor reliably
(perhaps running sed on /etc/issue?) I'll see about forwarding it
upwards.
