From f0119060ef1b9bd80e2cae487df1e4aedffb0e9b Mon Sep 17 00:00:00 2001
From: Oleksiy Obitotskyy <oobitots@cisco.com>
Date: Fri, 22 Jan 2021 09:12:48 +0200
Subject: [PATCH] dtc: Fix Makefile to add CFLAGS not override
Makefile override CFLAGS not extend them, so some of them
missing. Sources builds out of kernel tree and probably not all
options could be used (?). We need at least -fmacro-prefix-map/
debug-prefix-map to eliminate absolute path in binaries.
