-From b40c129ed2d53b69463883a5422dd4a012a398f9 Mon Sep 17 00:00:00 2001

-Subject: [PATCH 6/7] ldso: limited support for $ORIGIN in rpath
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Derived from:
-http://lists.busybox.net/pipermail/uclibc/2011-March/045003.html
-
-However, the above patch introduced '_dl_strchr' in ldso/ldso/dl-elf.c,
-and caused the following undefined referencing compiling error:
-
- | .../libdl.a(libdl.os): In function `search_for_named_library':
- | .../dl-elf.c:156: undefined reference to `_dl_strchr'
- | collect2: error: ld returned 1 exit status
-
-This problem would be reproduced through compiling gdb in static mode
-using uclibc.
-
-So, add the definition of '_dl_strchr' to fix it. The '_dl_strstr' is
-added as well.
