Gives me 
```
"clang-linker-wrapper" "--host-triple=x86_64-unknown-linux-gnu" "--cuda-path=/usr/local/cuda" "--linker-path=/usr/bin/ld" "-z" .....
"clang" --no-default-config -o /tmp/a.out.nvptx64.sm_89-954e0b.img --target=nvptx64-nvidia-cuda -march=sm_89 /tmp/input-nvptx64-nvidia-cuda-sm_89-945b9a.o
```
so the child of `clang-linker-wrapper` does not get the `--cuda-path`.
