[PATCH 2/3] build system: add target update-versions to propagate version

[David Bremner]

From: David Bremner <bremner at debian.org>

The version from file "version" is propagated to the man page and the
python bindings via sed. Note that the git version is ignored because
of the check for MAKECMDGOALS.
