If you plan to use a device without NEON (e.g. the emulator), you need a build without NEON:
$ export NO_NEON=1
Make sure it is set throughout the entire process.

The script will attempt to automatically detect if you have NDK v7, but you can override this.
If you do not have NDK v7 or later:
export NO_NDK_V7=1
or if you are sure you have NDK v7:
export NO_NDK_V7=0
