From d4714fd7aac9c5f499c406703bc437dc6cf72ef3 Mon Sep 17 00:00:00 2001
From: Steffen <steffen.winter@proton.me>
Date: Mon, 13 Feb 2023 17:32:16 +0100
Subject: [PATCH 1/3] Add custom error function for tests.
On musl systems, liburing cannot build examples and tests due to
it's usage of error.h. t_error calls fprintf(stderr, ...) and
exits.
Closes: #786
