[Cocci] [PATCH 1/2] autotools: unify the way to determine version information

[mcgrof@do-not-panic.com (Luis R. Rodriguez)]

From: "Luis R. Rodriguez" <mcgrof@suse.com>

The version information you get when you run: spatch --version
comes from what ./confgure.ac ends up figuring out for you.
The top level Makefile uses the same mechanism to tell you
and use the version information at build time, but if the
strategy is updated in one place it would need to be updated
in both places.

Avoid this duplicatin of work and instead just make version
information come from ./version.sh script. Then if we update
how we get the version information it just needs to be done
in one place.

We make the version.sh script use old shell mechanisms to be
able to work on any supported unix system.
