elfutils/elfutils-portability.patch

From: Tony Jones <tonyj@suse.de>
Subject: Elfutils portability patch
Version: 0.152
References: https://fedorahosted.org/releases/e/l/elfutils/0.152/elfutils-portability.patch
Upstream: yes

This patch contains portability fixes that are regarded as generally useful
by the community but are not accepted by the elfutils maintainer (and are
therefore not in the git repository).

Following change is removed from the patch (as Factory is built using
GNU_SOURCE and thus %a is interpreted as having a float param):

+       * addr2line.c (handle_address): Use %a instead of %m for compatibility.
