From f6e771032336f6af18997b3f9145d75301bb4da0 Mon Sep 17 00:00:00 2001 From: Baruch Siach Date: Thu, 25 Dec 2014 07:36:28 +0200 Subject: [PATCH] Makefile: clarify comment on .br-external handling The comment language may lead the reader to think that .br-external is removed whenever BR2_EXTERNAL is not set in the command line. Make it clear that BR2_EXTERNAL must be explicitly set to an empty value for .br-external to get removed.
