Android Platform Build with Linaro GCC 4.5 + graphite optimizations

Registered by Alexander Sack

As pointed out in our unofficial toolchain benchmarks for april toolchain, graphite options can give a significant boost in performance. We should try to enable graphite optimizations in our platform builds either all over or for places where they make most sense.
