ODROID-U3 packaging support (armhf Debian architecture tweaks) 

Hello, 

I've done the ground work to at least permit to have the XBMC packages building on Ubuntu LTS for ODROID-U3 hardware platform. The XBMC code changes that support ODROID-U3 is in the XBMC Piment Noir org Github. 

Cheers. 
sadly this doesn't work as it installs the cmake files as well, which clashes with the xbmc-addon-dev package. For now I don't have an easy solution.
