Cross Compiling a Rust project that uses crate inline-python

So, inside a rust project that I'm working on, we are using some python code(libraries) for functions that are not particularly compute heavy, but would require rather large amounts of code to implement. Unfortunately there are no crates that handle this particular work, and python had a library that was perfectly suited to these subtasks.

I believe I have narrowed down the problem to the need for a compiled python interpreter for the target architecture (based on: https://pyo3.rs/v0.9.2/building_and_distribution.html)
However, I am utterly unsure of how to get this .so file for each of the various targets or where to put it once it has been created. To add some context this is the --verbose part of the error when running

cargo build --target=aarch64-linux-android --verbose

error: build failed

The full error is several hundred lines long, so I have abbreviated it.

Note, this project compiles and works completely on the host system, which obviously has python@3.9 installed
