From 3daec2dd11a04955f95e8f65a48820103d84dbec Mon Sep 17 00:00:00 2001
From: Junling Zheng <zhengjunling@huawei.com>

Subject: [PATCH] uclibc support for elfutils 0.161
on uclibc systems libintl and libuargp are separate from libc.
so they need to be specified on commandline when we use proxy-libintl
then libintl is a static archive so it should be listed last since
elfutils does not respect disable-nls we need to link in libintl
We add a new option --enable-uclibc which will be used to control
the uclibc specific configurations during build.
Upstream-Status: Inappropriate [uclibc specific]
