From df16cc255bf2d208a61c7d9810e3be6685b697a6 Mon Sep 17 00:00:00 2001
From: Simo Sorce <simo@redhat.com>
Date: Tue, 26 Mar 2013 11:11:41 -0400
Subject: Switch to use standard GSSAPI by default

Make libgssglue configurable still but disabled by default.
There is no reason to use libgssglue anymore, and modern gssapi
supports all needed features for nfs-utils.
