Subject: [PATCH] Accepting request 921253 from
 home:manfred999:branches:Base:System

This is Part 1/2 to remove update-alternatives support from awk.
On linux systems, GNU software is usually considered the default implementation. There are a lot of scripts assuming gawk to be the
interpreter engine, as for very long time now, gawk is the default
interpreter for SUSE/openSUSE.
Gawk is POSIX compliant if the env variable POSIXLY_CORRECT is set,
and therefore should be able to run run all awk scripts seeking for compatibility.
This patch unconditionally makes gawk the default awk implementation by setting a symlink from /usr/bin/gawk to /usr/bin/awk.
