From cb1de93e1216fe33c4fed2e4c15dfb6251d6013f Mon Sep 17 00:00:00 2001 From: Ismael Luceno Date: Tue, 17 Mar 2026 08:59:34 +0100 Subject: [PATCH 6/8] Makefile: Implement configuration saving This way, changing a configuration variable is persistent; no need to specify them every time. The .config file is included twice so that only user-specified variables get updated. This is compatible with GNU make 4.4+ and NetBSD make and derivatives. Also added a distclean target to clean the .config file.
