branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Add a config option to enable the Xenomai registry, which allows accessing
internal Xenomai state.

[Thomas:
- add missing Config.in comment.
- rewrap Config.in help text.
- tweak the .mk file logic for the registry path to avoid the super
long line.]
