Subject: [PATCH] xmr-stak: drop gcc6 requrement (and cuda support)

    [ 86%] Building CXX object CMakeFiles/xmrstak_opencl_backend.dir/xmrstak/backend/amd/minethd.cpp.o
    nvcc fatal   : Unsupported gpu architecture 'compute_30'
    CMake Error at xmrstak_cuda_backend_generated_cuda_extra.cu.o.Release.cmake:220 (message):
      Error generating
      /build/source/build/CMakeFiles/xmrstak_cuda_backend.dir/xmrstak/backend/nvidia/nvcc_code/./xmrstak_cuda_backend_generated_cuda_extra.cu.o
    nvcc fatal   : Unsupported gpu architecture 'compute_30'
    make[2]: *** [CMakeFiles/xmrstak_cuda_backend.dir/build.make:84: CMakeFiles/xmrstak_cuda_backend.dir/xmrstak/backend/nvidia/nvcc_code/xmrstak_cuda_backend_generated_cuda_extra.cu.o] Error 1

CUDA support is broken for a while. Let's drop it along with gcc6 requirement.
