``ANDROID_HOME`` environment variable. We need to install toolchain
under ``$ANDROID_HOME/toolchain``. An user can freely choose the path
for ``ANDROID_HOME``. For example, to install toolchain under
``$ANDROID_HOME/toolchain``, do this in the the directory where NDK is
unpacked:

$ build/tools/make_standalone_toolchain.py \ $ unzip android-ndk-$NDK_VERSION-linux.zip
--arch arm --api 16 --stl gnustl \ $ cd android-ndk-$NDK_VERSION
--install-dir $ANDROID_HOME/toolchain $ export NDK=$PWD
The API level (``--api``) is not important here because we don't use
