Use aarch64-linux-android-4.9 for arm64 build (attempt #4)
GCC: 4.9 (which supports -fstack-protector)
Binutils: 2.24 (which supports gc-sections)
GDB: 7.7
NDK libraries are still picked up from prebuilts/ndk/*/4.8/*
GCC has been patched to disable codegen for calling
__cxa_throw_bad_array_new_length.
Source code has been sync'ed against the 2014-05-14 snapshot which
contains many important fixes (devirtualization, codegen, ...).
