Building IGT for android generates large numbers of warnings as the compiler used for android is more paranoid. If you make all warnings errors you would have to also fix a lot of warnings for android.

>We have this for check and distcheck internally. The whole point of Werror was to catch warnings as well when building, and letting us know so we can fix it. The problem is (unfortunately) that not all patches arrive thru m-l. Don't really know how much traction some CI/buildbot for i-g-t will have.
