"""Configuration for the Caffe2 installation targeted for Android.

To run the build, first create a standalone toolchain from the NDK root using:

./build/tools/make-standalone-toolchain.sh \
  --arch=arm --platform=android-21 \
  --toolchain=arm-linux-androideabi-4.9 \
  --install-dir=./standalone-toolchains/arm-linux-androideabi-4.9-android-21

(change the platform and toolchain if necessary) and update the
