We have to move the content of the 'webrtc/build/' directory up of one level (see crbug.com/611808 for further details).
To avoid a collision with the DEPSed build/ at the top level we are moving all the content of 'webrtc/build/' to different locations (see webrtc:7030 for the suggested locations).
