From 9d57d4353c82110c609f36f91986277343d4ee45 Mon Sep 17 00:00:00 2001
From: "Yann E. MORIN" <yann.morin.1998@free.fr>
Date: Wed, 8 Feb 2023 13:26:56 +0100
Subject: [PATCH] configure: allow overriding some tests

Some tests use AC_RUN_IFELSE, so they do not work for cross-compilation.

Allow the user to provide these results from the environment.
