Hmm, 'automatic GPU detection' doesn't sound good at all.

    sys-devel/clang: Disable CUDA target autodetection
    
    CUDA target autodetection causes sandbox failures, and even if it did
    not, it would cause the package to be set for build host's video card.
    Force the CUDA package detection to fail, in order to disable that.
