 From ticket:25851#comment:1
 LeanPlum is not included by default. It is only included if
 true (false by default) and MOZ_ANDROID_GCM must be true (which we set
 at configure time):

 From ticket:25851#comment:2
 Adjust is excluded at build-time, so we can ignore that. It is excluded
 if MOZ_INSTALL_TRACKING is not set. This is similar to LeanPlum - it
 requires MOZ_ANDROID_GCM, too. We could change the MOZ_INSTALL_TRACKING
 default value, too (being extra safe) - but currently it will not be

 This is safe as long as we don't include `--with-google-play-services`. We
 already include `ac_add_options --without-google-play-services` in
 `.mozconfig-android` so neither LeanPlum or Adjust are included.

 I also created a branch - `25906` in my repo - for review where we set the
 configure options as |false| by default, as another safety measure.

 In reality, even if leanplum or adjust were enabled, `mach configure`
 should fail because there is an additional dependency on specifying a
 `leanplum-sdk-file` and `adjust-sdk-file` which we don't include. But I'd
 prefer playing this safe.
