    gnu: mesa: Fix build on arm architectures.
    
    * gnu/packages/gl.scm (mesa)[inputs]: When building for an arm platform
    add python-pycparser.
    [arguments]: When building for aarch64 or armhf don't add kmsro as a
    gallium driver.
    * gnu/packages/python-xyz.scm (python-pycparser): Mark as a dependency
    for mesa.
