I have just put up prebuilt cross-compilation SDKs for the three most used Android architectures, along with instructions on how to use them and build the SDKs yourself if wanted. If you, @dstoker-cricut, and anyone else interested could try cross-compiling from linux (@v.gorlov reports a problem using them on a Mac) and test your Swift packages on Android, we could see how well it works. I haven't had any problems so far.
