From 5c43fd7954108bd138f7a1b4db4fb997ae1dc696 Mon Sep 17 00:00:00 2001 From: Willy Tarreau Date: Tue, 19 Jul 2022 23:44:46 +0200 Subject: [PATCH] selftests/nolibc: add a "defconfig" target While most archs will work fine with "make defconfig", not all will do, and it's not always easy to remember the most suitable choice to use for a specific architecture. This adds a "defconfig" target to the Makefile so that one may easily run "make -C ... defconfig" and make sure to clean and rebuild a fresh config. This is *not* used by default because we want to preserve the user's config by default. Signed-off-by: Willy Tarreau Signed-off-by: Paul E.
