$NetBSD: patch-configure,v 1.3 2017/07/12 13:56:00 hauke Exp $

Disable zeroconf explicitely, unless enabled - the distribution
appears not to allow for this.

We do not at this point support zeroconf via avahi. Since configure
does not allow for building without avahi, and native avahi is picked
up on some Linuxen, we disable all avahi tests unconditionally here.

Fix build on SunOS by disabling the isainfo bitness check
