aarch64 builders re-instanciated

Hi there, As requested by linaro (our host provider for aarch64), I've had to re-instanciate all of our aarch64 builders last week. It went smooth thx to ansible, but it seems like one last missing bug remained, this is now fixed as of the last 10 mins. Others builders issue are related to the usual offset with fedora repositories not published for all arches at the exact same time. Please cancel/resubmit your jobs as needed. Thx. -- - Nicolas (kwizart)
