This commit implements Christian Ege's suggestion in the meta-ros

Project depending on libeigen's headers can't be compiled with
gcc 7.1 because of the int-in-bool-context warning.
As suggested in
https://listengine.tuxfamily.org/lists.tuxfamily.org/eigen/2017/06/msg00013.html
it's easier to disable the warning for now until libeigen
fixes them.
