Add pre-built binary for Android

[Juhan280]

I was using gleam on Android using termux using the aarch64 linux pre-built binary but it was giving me dns error

After some discussion in discord we found out that it could be solved if I build the binary from source. However it takes a lot of time to build it that way. I would love to have a pre-built binary for Android

Hello! Is this something we could do today on GitHub actions? I don't know anything about compiling for Android I'm afraid.

I am not that experienced in rust. But i did some research. I think we could add the android target to target and include property of release.yaml

For reference
https://rust-lang.github.io/rustup/cross-compilation.html

My target is aarch64-linux-android btw

I tried but couldn't make it work

This article suggests it's possible with cross: https://reemus.dev/tldr/rust-cross-compilation-github-actions#heading-compiling-with-cross

I saw you tried to do so here: https://github.com/Juhan280/gleam/actions/runs/8767097805/job/24060032517

Seems like a library is missing (-lunwind from the error). I wonder whether it can be installed.

Alternatively, this stackoverflow thread had some success with cargo ndk¹: https://stackoverflow.com/questions/75909583/cross-compiling-rust-crate-on-windows-for-android

We will probably need to experiment with configuring those tools until we find a suitable configuration.

Actually, seems like this is a bug with cross, to be addressed soon by upstream (apparently already fixed on cross' main branch): cross-rs/cross#1222

So we should be able to wait for a new cross release.
