package/libbsd/0003-Handle-systems-missing-sys-cdefs.h.patch

From 11ec8f1e5dfa1c10e0c9fb94879b6f5b96ba52dd Mon Sep 17 00:00:00 2001
From: Guillem Jover <guillem@hadrons.org>
Date: Tue, 6 Mar 2018 01:41:35 +0100
Subject: [PATCH] Handle systems missing <sys/cdefs.h>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This is a non-portable header, and we cannot expect it to be provided by
the system libc (e.g. musl). We just need and rely on declaration that
we have defined ourselves in our own <bsd/sys/cdefs.h>. So we switch to
only ever assume that.

Fixes: https://bugs.freedesktop.org/105281

Backported from: 11ec8f1e5dfa1c10e0c9fb94879b6f5b96ba52dd
