<pre>
    I'm trying to build and run the libc on my machine using WSL (Ubuntu 24.04.1 LTS) on i7-9700K CPU. 
For building the project, I use the same cmake command provided on the [Libc's website](https://libc.llvm.org/overlay_mode.html#overlay-mode):
```
cmake ../runtimes -G Ninja -DLLVM_ENABLE_RUNTIMES="libc"  \
 -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ \
 -DCMAKE_BUILD_TYPE=Release 
```
Below is the error message that `ninja check-libc `outputs:
