I am trying build llvm locally on macOs M1.
The configuration:
```
cmake -B build -G Ninja -S llvm \
-DLLVM_ENABLE_PROJECTS="clang" \
-DLLVM_ENABLE_RUNTIMES="libcxx;libcxxabi;libunwind" \
-DLIBCXX_INCLUDE_TESTS=ON \
-DCMAKE_BUILD_TYPE=Release
ninja -C build check-cxx
```
Failed messages:
```

```
So why it building for macOS-x86_64? Did I configure something wrong and how to fix it?
Thanks.
