Fixes #18430 and possibly #18434.

#18413 caused error on blackwell local build because native will be treated as 120-real but is not captured by the regex.

Tested with or without docker (with a blackwell GPU). Seems OK.

Could you share the build command? I tried (locally, without docker) -DGGML_NATIVE=ON -DGGML_CUDA=ON -DLLAMA_BUILD_TESTS=OFF with CUDA 13.1 and it builds fine.
