From 94028b16e56c8eef1aa02dcc4da268a0e471b4ea Mon Sep 17 00:00:00 2001
From: Hongxu Jia <hongxu.jia@windriver.com>
Date: Fri, 23 Aug 2019 10:19:48 +0800
Subject: [PATCH 3/4] musl-utils

Provide missing defines which otherwise are available on glibc system headers

Alter the error API to match posix version
use qsort instead of qsort_r which is glibc specific API

Signed-off-by: Khem Raj <raj.khem@gmail.com>
Upstream-Status: Inappropriate [workaround for musl]

Rebase to 0.177
