Howabout something like this:

commit eb8387cb0eda32a18880664eb5f0ca5c8bf05b45
Author: Riku Voipio <riku.voipio@iki.fi>
Date:   Thu Jun 18 22:44:31 2009 +0300
Subject: linux-user: include futex defines directly

Since some common distributions have broken linux/futex.h, stop
including it. Instead add the defines directly.
