From 3f7fad001e4fe74a89b60d2e217750baaf3b0392 Mon Sep 17 00:00:00 2001
From: Charles Kerr <charles.kerr@canonical.com>
Date: Tue, 10 Jun 2014 23:04:52 -0500
Subject: Don't build the hw-alarms pieces if ubuntu/hardware/alarm.h can't be
 found. Don't require libplatform-hardware-api-* unless the arch is armhf,
 i386, or amd64.
