From 7396ca2979ec9b954f015da48444fa7068c86d11 Mon Sep 17 00:00:00 2001
From: Thierry Vignaud <tv@mageia.org>
Date: Fri, 27 Jul 2012 17:38:35 +0000
Subject: backported from rpm.org (Mark Wielaard <mjw@redhat.com>, 2011-05-25):

Add -r flag to find-debuginfo.sh to invoke eu-strip --reloc-debug-sections.
- This is a new option to eu-strip that strips out/resolves relocations
  between .debug_* elf sections in ET_REL files. This can save a lot of
  space for kernel module.
