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 <w@1wt.eu> Signed-off-by: Paul E.
