From 7699704e011db864c56f333bce9936a36522fb79 Mon Sep 17 00:00:00 2001
From: Tim Gardner <tim.gardner@canonical.com>
Date: Thu, 9 Dec 2010 08:16:52 -0700
Subject: [PATCH 1/2] UBUNTU: [Config] Fix FTBS caused by new binutils
New assemblers need -march=armv7-a+sec on command line or
.arch_extension sec inline to enable use of the smc instruction.
This patch uses as-instr to check the latter to conditionally
enable the former in AFLAGS for files that use smc.
Checked on both old and new binutils to verify that it does
not break old versions.
