@jhuber6 : Interestingly enough, this exposed what looks like an issue with the new driver -- it will apparently attempt to run linker on empty inputs.
I believe it's an issue independent of this patch and will need to be fixed separately.

```
bin/clang -target powerpc64le-ibm-linux-gnu -ccc-print-bindings -fsyntax-only --cuda-gpu-arch=sm_30 --cuda-gpu-arch=sm_35 --offload-new-driver /usr/local/google/home/tra/work/llvm/repo/clang/test/Driver/cuda-bindings.cu

# "nvptx64-nvidia-cuda" - "NVPTX::Linker", inputs: [(nothing), (nothing)], output: "/tmp/cuda-bindings-0bbbdf.fatbin"
# "powerpc64le-ibm-linux-gnu" - "clang", inputs: ["clang/test/Driver/cuda-bindings.cu", "/tmp/cuda-bindings-0bbbdf.fatbin"], output: (nothing)
