Bug#764732: gcc-4.9: broken -O2 optimizations on armhf



the escalation is wrong. there exist several workarounds for it (lowering the
optimization, using gcc-4.8, ...). I asked the ARM porters to address this
properly (Hector on IRC agreed to forward this), however I don't see any
progress here. Now CCing debian-arm explicitly.
