    gnu: x265: Build 10-bit and 12-bit libraries.
    
    * gnu/packages/video.scm (x265)[arguments]: Add configure-flag to set
    %output for the other builds. Add custom 'build-12-bit and 'build-10-bit
    phases to build their respective versions. Add a custom phase to install
    the 10-bit and 12-bit libraries.
