      Linaro is maintaining some advanced/more stable/experimental versions

      of gcc, especially for the ARM architecture.

      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.
