I not really understand the motivation having arch / noarch. Is the any
article on this?

You can check real builds on:
Patches on top of the master branch:
https://travis-ci.org/devel-opi/xenomai-fork/builds/501878686 (Ran for 28
min 59 sec)

Patches on top of the next branch (failed for some reason):
https://travis-ci.org/devel-opi/xenomai-fork/builds/502131163

Travis runs 5 parallel jobs simultaneously until other are pending.
