Add compilation target android-arm64 (#208)

Browse Source 
* Add android-arm64 support

cd bgfx
export ANDROID_NDK_ROOT=$NDK_ROOT
export ANDROID_NDK_ARM=$NDK_ROOT/toolchains/aarch64-linux-android-4.9/prebuilt/linux-x86_64
export ANDROID_NDK_CLANG=$NDK_ROOT/toolchains/llvm/prebuilt/linux-x86_64
make android-arm64

* Expect ANDROID_NDK_ARM64 to define the compilation aarch64 toolchain

Using _ARM64 will generate less conflict in configuration files than
reusing the _ARM var.

For example, to setup an android-arm64:

export ANDROID_NDK_ROOT=$NDK_ROOT
export ANDROID_NDK_ARM64=$NDK_ROOT/toolchains/aarch64-linux-android-4.9/prebuilt/linux-x86_64
export ANDROID_NDK_CLANG=$NDK_ROOT/toolchains/llvm/prebuilt/linux-x86_64

make android-arm64
