Right, there's no support for following forks or execs in the RSP yet.

"run" doesn't work with "target remote" either. If that is succeeding,
it's because it's actually running the default native target,
which is obviously bogus. If that can't be fixed easily, we should skip
the test on remote targets. But if you see failures related to fork
afterwards, maybe that because you have a customboard file that runs
in extended-remote?
