From ea7e0fba6da734e5f99f84d10d456ceaaed05883 Mon Sep 17 00:00:00 2001
From: Andrey Zhizhikin <andrey.z@gmail.com>
Date: Sun, 31 May 2020 20:40:25 +0000
Subject: [PATCH] flags: do not override CFLAGS from host
Some build systems set CFLAGS in environment before the build, but they
got overridden by CFLAGS immediate assignment operator.
Replace immediate assignment with append directive, so the former
definition of CFLAGS gets properly expanded.
Upstream-Status: Submitted [https://github.com/OP-TEE/optee_client/pull/211]
