-fstack-protector only needs a small amount of runtime support to work on native builds. It increases code size by ~1.5% on ARM/MIPS; -fstack-protector-strong adds 3-4%. This is disabled by default and must be enabled by passing '--with-stack-protector' to configure. Change-Id: If952e711d3673c9b469895f08c7bff70b3d95df6
