Still, I believe the bug should be fixed at the source.

Maybe these bots do so much traffic that nobody really cares about them.
Do they directly address the author and the corresponding maintainer ?
(if that ever happens to one of my drivers, please let me know)

Could we set up a separate build bot for those configurations, with a
different from: address and an a special warning text, so maintainers
quickly see they *should* pay attention.

IMHO, this is primarily a problem of handling the massive traffic
on lkml and sorting out whats relevant for oneself.
