From 82e57b704a4f7149112f7d5bca9199aa9953e51e Mon Sep 17 00:00:00 2001
From: Ricardo Salveti <ricardo@foundries.io>

Subject: [PATCH] Makefile: prefer append on CFLAGS / LDFLAGS

Append allows an external build system to pass custom cflags/ldflags
to the local build system (make).

Useful with Yocto / OE as additional options can be given besides what
is set with a force set in the Makefile.
