After trying $ANDROID_HOME/ndk-bundle, we also try $ANDROID_NDK_HOME.
ANDROID_NDK_HOME is advised in this NDK sample code wiki:
https://github.com/googlesamples/android-ndk/wiki
Mentioned in the Bazel buildsystem Android app tutorial:
https://docs.bazel.build/versions/master/tutorial/android-app.html
On Ubuntu, the google-android-ndk-installer leaves the NDK in
/usr/lib/android-ndk, and it seems to be up to the user to set
ANDROID_NDK_HOME.
On Arch Linux, the android-ndk package installs the NDK into /opt/android-ndk
and sets ANDROID_NDK_HOME to there using an /etc/profile.d/file
