From 75ef683781cdb3c853f94acfccd25b7499be761c Mon Sep 17 00:00:00 2001
From: Jaco Kroon <jaco@uls.co.za>
Date: Mon, 30 Mar 2026 21:48:39 +0200
Subject: [PATCH] tests: Use abs_srcdir for tests.

Currently the assumption is that srcdir is a relative path, which is a
false assumption if configure was invoked with an absolute path as per
some (Gentoo) automated build systems.
