ReLinker fails to find dependencies recursively on Android-16

[ViliusSutkus89]

Hello team, thanks for the project!

Trying to use it but can't seem to get it working on older Android devices.

I've put together a trivial test case to illustrate my issue.
It's an Android JNI project with min SDK set to 16 and Android STL set to "c++_shared".
Shared STL implies that my native library depends on libc++_shared.so.

I load my native library using:

ReLinker.recursively().log(logcatLogger).loadLibrary(getApplicationContext(), "native-lib");

Here's the output from logcat:

12-24 00:00:43.912 14207-14207/? D/---ReLinker: Beginning load of native-lib...

It works nicely if I load libc++_shared.so beforehand either manually by System.loadLibrary or using ReLinker, but that kind of defeats the purpose.

Failure happens on "system-images;android-16;default;x86" emulator image.
Works nicely on real (non-emulator) Android-25 device.

Let me know if I'm missing something obvious.

Thanks,
Vilius
