$NetBSD: patch-configure,v 1.1.1.1 2012/02/10 17:57:38 drochner Exp $

Remove dependencies on libxml-2.0 and libxslt shared libraries.
configure.ac equivalent of:

   -# Dependecies
   -PKG_CHECK_MODULES(YELP_XSL,
   -[
   -       libxml-2.0 >= 2.6.12
   -       libxslt    >= 1.1.8
   -])

There are no C programs, so we don't need compile flags for the
above libraries. The dependency on libxml2 is present indirectly
in the dependency on itstool. I should be able to install yelp-xsl
without having the above shared libraries.

One could argue that I needn't put the DEPENDS lines in the Makefile.
