 Note that I reduced that from once per hour to once per day. Unfortunately I
forgot why I did that :-)

 I think you have better access to machines that can do such a thing, so could
you set it up? Go to the triggers section on
https://gitlab.com/buildroot.org/buildroot/settings/ci_cd, create a trigger
token, and use it in

curl -X POST \
     -F token=TOKEN \
     -F ref=master \
     https://gitlab.com/api/v3/projects/2648174/trigger/builds

 I would wait a bit with that until any remaining issues on the gitlab side have
been ironed out. One issue I found already is that there seems to be some
throttling going on in the git.freescale.org repositories, and our 12 parallel
freescale defconfigs are hit by it.

 Also, it turns out that the "free runners" have become a lot slower since I
first tried it, it now takes something like a day for all the defconfigs to
build. So maybe we should consider setting up our own runner after all...
