That is a copy of AdaCore's RTS, so it retains their licensing.

And that is derived from someone else's work, they used the MIT license.

It doesn't really matter what license these build scripts, including
GPRs, use, because they won't be part of a deliverable binary. So long
as the license terms allow you to use them for a build, of course! For
demo code, if I haven't already, I'll be using this:

The Discovery boards are intended for exploration, so it seems
reasonable for them to impose this restriction. I need to work out
porting at some point.
