From 6dd3f13e4239a8c2b1e60687d7321bc0df614f33 Mon Sep 17 00:00:00 2001 From: Michal Marek Date: Thu, 16 Jul 2015 18:23:53 +0200 Subject: [PATCH] kbuild: Do not pick up ARCH_{CPP,A,C}FLAGS from the environment Initialize the ARCH_* overrides before including the arch Makefile, to avoid picking up the values from the environment. The variables can still be overriden on the make command line, but this won't happen by accident.
