[Python-modules-team] Bug#681270: causes FTBFS of pymvpa2 on s390x: TypeError: Improper input parameters in leastsq call

and keeping things going forward -- building current head of scipy

at once gcc warnings  already become informative 
(once again diff from s390) and might be actually pointing to the issue we are enjoing
