See  bug 867013 .

Under the Simple Chrome shell (cros chrome-sdk), the GL headers are provided by the //ui/gl dep, but on the linux-chromeos build, the GL headers are provided by the system. Currently remoting/client/display doesn't have dependency on //ui/gl yet, and fails to build on ChromeOS. We currently exclude the display target from ChromeOS, but for longer term we should fix the code to make it work.
