Trying to build [llvm 20.1.8](https://github.com/llvm/llvm-project/releases/tag/llvmorg-20.1.8) using `Ninja Multi-Config` as generator fails with error:
```sh

```
Build command:
```sh
$ cmake -DBUILD_SHARED_LIBS=ON -DCMAKE_C_COMPILER=clang \
-DCMAKE_CXX_COMPILER=clang++ -DLLVM_BUILD_TESTS=ON \
-DLLVM_ENABLE_ASSERTIONS=ON -DLLVM_OPTIMIZED_TABLEGEN=ON \
-DLLVM_ENABLE_PROJECTS=clang -DLLVM_USE_LINKER=lld \
-DLLVM_USE_SPLIT_DWARF=ON -G "Ninja Multi-Config" \
-B build_temp
```
I have a preinstalled clang from pacman:
```sh
clang version 20.1.7
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin
```
