Bug report

Bug description:

After #118307 , the developer needs to install LLVM 18 if they want to build CPython locally. But LLVM <= 17 is the most commonly used version in a lot of distributions of Linux( Like Ubuntu, Arch, Fedora)

I propose to add new environment variables like PYTHON_JIT_LLVM_VERSION to allow people override the default LLVM version requirement locally

CPython versions tested on:

CPython main branch

Operating systems tested on:

Linux
