Include source code for ELFs

[dalb8]

There are some prebuilts in src/main/jni. Could these be built from source code too?

Trying to build from https://github.com/glance-/pulseaudio-android-ndk and replace the binaries with that to smooth out any of these issues

I've been trying but the patches don't apply.

I believe the patches are already applied at the versions which are linked as submodules (for json-c anyway). I have a build, but then have issues where one of the libraries asks for a versioned .so file (so.x.x) and java's load library isn't happy with it (although using absolute paths works o.k.)
