If ubuntu-20.04 is an LTS release it might be interesting to have. Is
it an LTS release for Arm (I am not an Ubuntu user and don't know if
they officially support something other than x86_64 as LTS release)?
If not I think just having the latest is better.

Yes for 64bit, unclear for 32bit systems. As far as I understand for
32bit systems --enable-targets=all is broken, but only for sim. So we
might have to configure with --enable-targets=all --disable-sim

Could it be both? The idea behind to user try branches is that you can
run the buildbot builders as if doing a "real" build. There are not
many people using the try branches at the moment, so it isn't really
that much more work (also the configuration is simply adding an
identifical builder to the try-scheduler).

Cheers,
