So, it's really good that you add "known good" versions so that if
someone runs into a problem around toolchain version compatibility,
they know what to use. But anything in edk2-platform should be kept up
to date so that it builds on current operating systems.

And I'd prefer for known versions to include toolchain profile and
versions of tools (so people don't need to go run lookup tables on
what versions are included in what distro).
It's fine (even good) to state "as included in distro X release Y",
but I want more granularity. Because I may well have a GCC9 lying
around in a vm somwehere, and then I can use that instead of hopping
off setting up a dedicated thing to build a specific platform.

No issue with this part.
