This series is still missing changes to enable build on all targets
during CI, including cross-compiles, to prove that we're doing the
correct thing on all our targetted platforms. That's a must have
before considering it suitable for merge.
But we're not—in particular it's still using several features not in all supported distros.
I also believe we should default to enabling rust toolchain by
default in configure, and require and explicit --without-rust
to disable it, *despite* it not technically being a mandatory
feature....yet.
I guess the detection could be done, but actually enabling the build part needs to wait until the minimum supported version is low enough.
