Do you prefer we have 
```
$ ld.lld --version
LLD 19.0.0 (https://github.com/yugier/llvm-project.git 4134b33c6a362cb462b335177d6d9e8235f04309), compatible with GNU ld
```

or 
```
$ ld.lld --version
LLD 19.0.0, compatible with GNU ld (https://github.com/yugier/llvm-project.git 4134b33c6a362cb462b335177d6d9e8235f04309)
```

Thank you!
