I was trying this 
```
./clang-repl   --oop-executor=$PWD/llvm-jitlink-executor   --orc-runtime=/build/anutosh491/llvm-project/build/lib/clang/22/lib/x86_64-unknown-linux-gnu/liborc_rt.a
```
And was noticing that the orc-runtime flag isn't respected through the config.

Discovered it is not being set !
