Not having to provide another sufficiently recent clang/llvm-link binary to pass with `-DLIBOMPTARGET_NVPTX_CUDA_COMPILER`/`-DLIBOMPTARGET_NVPTX_BC_LINKER`.

D95466 <https://reviews.llvm.org/D95466> seems to have removed the checks for a working Clang at configure-time. If it was still there, this patch would have disabled them since the Clang in the repository with OpenMP would be the most recent and known to support all required features. This also makes it ideal default if available.
