[alsa-devel] [alsa-utils][PATCH 3/5] configure.ac: add a check for rst2man, a reStructuredText man page generator

[Antonio Ospite]

Define a USE_RST2MAN conditional so that, when available, rst2man can be
used to generate man pages from reStructuredText source files.

The code follows what is done to check for xmlto.

On Debian system, the rst2man executable is provided by python-docutils
or python3-docutils.
