Endeavouring to install `so` in Termux with `cargo` without success

[b9Joker108]

Describe the bug
I have endeavoured to install so in Termux with cargo, without success.

To Reproduce
Steps to reproduce the behavior:

1. cargo install so
2. I checked appropriate environment variables are set:

❯ echo $JAVA_HOME
echo $PATH
/data/data/com.termux/files/usr/opt/openjdk-17
/data/data/com.termux/files/home/.local/bin:/data/data/com.termux/files/home/.local/share/basalt/source/pkg/bin:/data/data/com.termux/files/usr/share/texlive/bin/aarch64-linux:/data/data/com.termux/files/home/.local/bin/1password_cli_v2:/data/data/com.termux/files/home/.zi/polaris/sbin:/data/data/com.termux/files/home/.zi/polaris/bin:/data/data/com.termux/files/usr/bin:/data/data/com.termux/files/usr/bin/texlive:/data/data/com.termux/files/home/.cargo/bin:/data/data/com.termux/files/home/markdown.index:/data/data/com.termux/files/home/.dotfiles/scripts/sh.scripts:/data/data/com.termux/files/home/bin:/data/data/com.termux/files/home/browsh/:/data/data/com.termux/files/home/install/bin:/data/data/com.termux/files/usr/opt/openjdk-17/bin

I got the following error output:

...

I have never built this on Android, but I imagine this is an issue with your environment. You'd probably have better luck opening an issue with the jni crate, or perhaps the webbrowser crate that is pulling it in.

If you'd like, I can feature gate the webbrowser dependency which is only used for opening a browser and navigating to the specific question/answer on stackexchange. Then you could e.g. cargo install so --no-default-features --features termion-backend and just not have the browser functionality.
