Huh, what's GNU Rust?

Okay. What's implicit here is that we in fact don't use this script at all at the current point in time for our MinGW build, we rather use the "install-sdk.ps1" script. I assume it will be wired up in the next step, so let's read on.

Okay, so installing Rust is the only thing we will want to do on both MSVC and MinGW builds.
