CUDA: forward unknown flags to host compiler when possible.
Starting with CUDA 10.2 the nvcc compiler has gained support
to automatically forward unknown flags to the host compiler.
This behavior is highly desired as projcts that mix CUDA, C, C++
run into situation where flags such as `-pthread` which aren't
supported by nvcc, are being applied to all source files and
therefore break CUDA compilation.
