The packaged version of the `libc` library does not depend on the CUDA installation because it only uses `clang` and emits LLVM-IR. However, for testing we directly need the CUDA toolkit to emit and execute the files. This patch explicitly passes `--cuda-path` to the relevant compilations for NVPTX testing.
