The multiqueue branch is a private branch, it's known broken on many
configs at the moment.

OK. Sorry my script just blindly build tests every new/updated branches
in the tree. It does try to reduce noise level by remembering all warned
error messages. However if it still presents a problem to the private
branches, I can either explicitly blacklist "multiqueue", or let the
script automatically skip commits whose "^Signed-off-by:" is still
missing.

Thanks,
