joystick: linux: Avoid checking for gamepad mapping each frame The information whether a specific joystick can be used as a gamepad is not going to change every frame, so we can cache the result into a variable. This dramatically reduces the performance impact of SDL2 on small embedded devices, since the code path that is now avoided was quite heavy. Fixes #4229.

Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. It is used by video playback software, emulators, and popular games including Valveās award winning catalog and many Humble Bundle games.
More extensive documentation is available in the docs directory, starting with README.md
