Those versions have not been blessed by the gcc comunity (nor have they been cursed either!), but they look to be pretty much stable, and even more stable than the upstream versions. YMMV... If you do not know what this Linaro stuff is, then simply say 'n' here, and rest in peace. OTOH, if you know what you are doing, you will be able to use and enjoy :-) the Linaro versions by saying 'y' here.
