From 184f51099471341715bc81a4c09b56a3c6f9d687 Mon Sep 17 00:00:00 2001 From: Joel Stanley Date: Mon, 22 Jul 2019 12:32:44 +0930 Subject: [PATCH] Makefile: Add EXTRA_CFLAGS variable Distributions packaging dtc may need to set extra flags. Currently when they do that it overrides the ones set by the makefile. This is particularly problematic when compiling without yaml, as the yaml detection is ignored. ld: dtc.o: in function `main': dtc.c:(.text.startup+0x718): undefined reference to `dt_to_yaml' This patch provides a EXTRA_CFLAGS variable that is added to the list of CFLAGS, and can be set on the command line when packaging.
