I wanted to be doing some testing and development work with switching LLVM versions. This helps us uninstall the right content more frequently, thus making the swap between versions cleaner and easier.
And this also lets us print a warning of the user's versions mismatch those in the repository (may be intentional, so we just print a warning so that the user is aware).
This is temporarily a bit noisy, but you can quickly silence it by doing a simplemake -C deps uninstall
or a more aggressiverm -rf usr
