From 29551cacca6df9cd8bcf7223ae4383a27fd23557 Mon Sep 17 00:00:00 2001
From: Theodore Ts'o <tytso@mit.edu>
Date: Thu, 4 Sep 2008 22:36:52 -0400
Subject: [PATCH] Fix e2initrd_helper, blkid, and fsck from linking with
 unneeded libraries

... especially when using ELF shared libraries.  We only need to link
with a library if the executable uses that library directly.
