From f70602be19ff8042c369ea33b29f90b8c0f5d02e Mon Sep 17 00:00:00 2001
From: "Peter S. Mazinger" <ps.m@gmx.net>
Date: Wed, 28 Sep 2005 12:34:41 +0000
Subject: Remove ar-target and shared targets, at build time now we traverse
 the tree only once. Generalize all toplevel makefiles. Make sure, that
 libdl.so is built against libc.so and not libc.a
