[WINEDOCS] Check for nsgmls

[Francois Gouget]

With the new po4a nsgmls is the last external dependency. Po4a will now 
correctly detect that it is missing and fail (it used to go on without 
translating anything) but it would be nice to warn the user beforehand 
during the configure check. Note that this is a warning with suggestions 
as to which package to install, not a fatal error. So the user can go on 
just like when docbook2html is missing.

I am just sending the configure.ac diff because my autoconf version is 
different which results in a big configure diff. So you will need to run 
autoconf and commit configure too.

Changelog:

  * configure.ac

    Check for nsgmls and warn the user if it is missing.
