From 9f9ab4922338d58f5adf8353286039eae09e1c2f Mon Sep 17 00:00:00 2001
From: Joakim Tjernlund <joakim.tjernlund@transmode.se>
Date: Wed, 6 Oct 2004 07:34:17 +0000
Subject: Puts common defines into dl-defs.h (in ldso/include) from dl-elf.h
 and dl-cache.h and make use of it. Also disables the lib-path-redundancy
 check for the case the cache is not used. Makes use of _PRELOAD_FILE_SUPPORT.
 From Peter Mazinger.
