The `RID` already has the host triple available I thought https://github.com/llvm/llvm-project/blob/3734e4c0c4966f794b9588445448004fee769ab9/clang/lib/Driver/ToolChains/ROCm.h#L169. Is the issue the fact that we probably make one for the GPU toolchain? If it's an unrecognized triple it should probably just give up.
