Ok, could you try if you can reproduce if you do a monorepo build with:

```
cmake -G Ninja <source>/llvm -DCMAKE_BUILD_TYPE=RelWithDebInfo -DLLVM_CCACHE_BUILD=ON -DLLVM_TARGETS_TO_BUILD=host -DLLVM_ENABLE_PROJECTS='clang;compiler-rt' -DLLVM_ENABLE_PER_TARGET_RUNTIME_DIR=OFF
```

(`-DLLVM_ENABLE_PER_TARGET_RUNTIME_DIR=OFF` should be the key option, the rest is just my "quick build" defaults)
