The gtk-doc wrapped binaries use XML_CATALOG_FILES to perform XML catalog
lookup and come with docbook-xsl within the variable which fixes the
docbook-xsl stylesheet lookup related failures with these packages.
This makes it unnecessary to include libxml2 as the cause of error was usually
with the gtk-doc binaries.
