+Subject: [PATCH] tools: fix building manpages with lxml 6.1.3
+
+manpages build fails on Arch with new lxml:

+The above exception was the direct cause of the following exception:

+    _xml = make_page(_template_path, _xml_files)

+    raise ValueError('failed to process ' + page) from e
+ValueError: failed to process ../src/man/hostname.xml
+
+Relying on XMLParser() defaults leaves the external parameter entity
+used to load custom-entities.ent unresolved. Request entity resolution explicitly.
