ghc-7.10 branch : Please cherry-pick 1a4374c1 from master
commit 1a4374c1e246d81a5c1d00a720919804093a8241 Author: Erik de Castro Lopo <firstname.lastname@example.org> Date: Mon May 4 23:39:31 2015 +0000 arm: Force non-executable stack (part 2) This was supposed to be part of commit 63a10bbc42 but I pushed from the wrong machine. This fixes cross compiling to arm.
63a10bbc42 has already been cherry-picked to this branch.
Without this, cross compiling to arm is broken.
