What time-line do you have in mind for this fix? If you are in charge
and can make this happen within a day, giving cmake + ninja a chance seems
OK.

However, if the owner of the buildbot is not known or the fix can not come
soon, I am in favor of disabling the noise and (re)enabling it when someone
found time to address the problem and verify the solution. The cost of
buildbot noise is very high, both in terms of developer time spent, but
more importantly due to people starting to ignore them when monitoring them
becomes costly.

Best,
