I'm not sure if this is a realistic usecase or one we care about, but if we have a single option would we lose the ability to have different offload targets for different offloading languages at the same time? Like `-fopenmp -fopenmp-targets=amdgcn -fsycl  -fsycl-targets=nvptx64`. I guess if we really wanted to support that we could add some special optional syntax to offload-targets.
