device: Add device support for the Broadcom Raspberry PI
Add mkspec for the Raspberry PI platform to be used in conjunction with the -device support in configure. This allows you to build Qt with the application libraries provided by the Raspberry PI foundation. The Raspberry PI is described here: http://en.wikipedia.org/wiki/Raspberry_Pi and its use with Qt is documented here: http://wiki.qt-project.org/Devices/RaspberryPi Change-Id: Ib8d11d0a469edaaf34ccc04cf33a42a725fc2bdb Reviewed-by: Girish Ramakrishnan <girish.1.ramakrishnan@nokia.com> Reviewed-by: Samuel Rødal <samuel.rodal@nokia.com>
