Wow, has it really only been three years that configure has acted this
way?  But anyway, after testing on a system that has opensp installed
but not docbook, I confirm that the DocBook test falls through quickly
pre-v11.  Agreed then that we only need this change in 11 and up.

Right.  That also seems like a good place to add a hint about setting
XMLLINT to 'xmllint --nonet' if you don't want remote fetches to happen
while building the docs.  Shall we do that instead of applying the
patch you posted earlier?
