[PATCH] D150136: [Clang] Change default triple to LLVM_HOST_TRIPLE for the CUDA toolchain

tra added a comment.

The change may be an improvement, but we may still have a potential issue here.

E.g. ideally we may want to be able to cross-compile a CUDA app on a powerpc or ARM build host targeting NVIDIA GPU on a x86 host. So, the compilation tools would need to be found for the powerpc/arm host, but the the pair of triples used during compilation would have to be x86 and nvptx.

In this situation the LLVM_HOST_TRIPLE would not be the right triple at all. Does OpenMP currently handle the cross-compilation scenario above?
