From 22537ffc1a86b3f483bd6ff0af9bd89880160f0c Mon Sep 17 00:00:00 2001
From: Christoph Reiter <reiter.christoph@gmail.com>
Date: Sun, 25 Jul 2021 13:54:12 +0200
Subject: [PATCH 114/N] build: Disable checks for dlopen/dlfcn
While it is (potentially) available with mingw we don't want to use it, so skip any
checks for it.
