ax_need_awk

Check if an awk implementation is available. Bail-out if not found.

This work is heavily based upon testawk.sh script by Heiner Steven. You should find his script (and related works) at <http://www.shelldorado.com/articles/awkcompat.html>. Thanks to Alessandro Massignan for his suggestions and extensive nawk tests on FreeBSD.
