The NDK doesn't have access to `android/set_abort_message.h`, so use
an extern declaration instead for API 21. For older releases, just use
`__assert2`, which will report to logcat and/or the tombstone for some
older releases.

In Android, stderr only goes to the console, and as such will only ever
be seen by adb shell users. Since very few developers will ever actually
see that, also send the abort message to logcat and the tombstone.
