This isn't how the vast majority of software behaves, where enabling tests does not affect the codegen of the to-be-installed build artifacts.

It's not just an issue for source distros like Gentoo, but really every linux distribution and in-house user of flang. It means that every release pipeline has to build flang twice just to run the tests (which many distros generally do for all packages)

I'm aware that `fir-opt` is mainly used in flang development, but if you do a quick github search you'll find that dozens of distributions and other software providers have it listed in package BOMs / summaries and similar, meaning it's been distributed to users for a while now.
