Fix llvm build error

Otherwise we get error: externally-managed-environment.

I'm not sure if this would be the best way to handle the issue, but we are already doing this anyway (in Dockerfile, for example).

Hi, what is the OS you used? We usually run build_llvm.sh in Ubuntu, MacOS and Windows and didn't find the issue. The --break-system-packages is added in Dockerfile and workflow since sometimes the OS in them is a little old, had better not add it to build_llvm.sh if not needed.

on macOS i have seen the error.
i don't know the exact cause or the correct fix.
i usually just remove --user and use virtualenv.

Yes, maybe we can just manually update the script and had better not add --break-system-packages for many files and commit them, not sure whether it will cause unexpected behavior.

Thanks for the explanation! Yes, I am using Mac 14.5, and it seems thatI this error only happens in newer versions of Python.
I'll close this PR for now.
