for how to provide a symbolic backtrace on Linux and MSYS2.
Add a "Crash bugs" section the the issue template with a link to said
README.md section.
Add a link to the Joystick page in the Arch Wiki so that users hopefully
use it to troubleshoot their joystick issues before filing an issue.
Also note that any joystick issues would be SDL related.
