The attached patch adds a test for libxslt/xslt.h and only builds
contrib/xml2 if it's found, which I think should handle Peter's
objection, as well as unbreak the buildfarm. (The patch is large because
cvs diff seems to have behaved a bit oddly with the configure script -
but otherwise it's fairly minimal).
