Sounds good, lets do it, please respin with that.

Right now each selftest subdir has a config file which lists dependencies,
perhaps it makes sense to have another standardized file there (e.g. 'deps')
which lists user space dependencies, so it's immediately visible what is
needed to run all tests from there. Thoughts?

As far as I'm aware the intel lkp-tests bot seems also to regularly run
the kselftests for x86, if also done from arm side e.g. on latest mainline,
even better.
