From 72fc70ed0ae1a78b2c0d65e0589319cdde098eee Mon Sep 17 00:00:00 2001 From: Douglas Raillard Date: Wed, 28 Dec 2016 14:47:50 +0000 Subject: [PATCH] build: Use separate CFLAGS for tools Sharing the same CFLAGS for both the firmware and host tools is not useful and can lead to compilation failure when CFLAGS is set on the command line. This patch make MAKEOVERRIDES special variable empty so make's command line variable definitions are not implicitly forwarded to sub make invocations. However, make options are still forwarded like "-s" option to make the build silent.
