Subject: [bug#43823] [PATCH 2/3] gnu: knot: Build the Info manual.

From: Simon South <[email-masked]>
Date: Mon, 5 Oct 2020 20:27:47 -0400

This also silences a configure warning about the "sphinx-build"
command being unavailable.

* gnu/packages/dns.scm (knot)[arguments]: Add "build-info" and
"install-info" phases.
[native-inputs]: Add texinfo and python-sphinx.
