From 4c797d3b559ba51bd9ccd9a2036245819acce843 Mon Sep 17 00:00:00 2001
From: Chen Qi <Qi.Chen@windriver.com>
Date: Thu, 23 Mar 2023 10:54:21 +0800
Subject: [PATCH] tools: Add error.h for non-glibc case
error is glibc specific API, so this patch will mostly not accepted
upstream given that elfutils has been closely tied to glibc
This is a OE specific workaround for musl.
Upstream-Status: Inappropriate [OE Specific]
