Cannot compile raylib for Android target

Issue description

I cannot compile raylib for Android target.

I get the following error:

$ mingw32-make PLATFORM=PLATFORM_ANDROID
...
core.c:5306:9: error: use of undeclared identifier 'gestureEvent'
        gestureEvent.position[i].x /= (float)GetScreenWidth();
        ^
core.c:5307:9: error: use of undeclared identifier 'gestureEvent'
        gestureEvent.position[i].y /= (float)GetScreenHeight();
        ^

I think this is caused by the changes made on this commit: 803094f

Environment

• Windows 10

This is an easy fix, I did this:
At the beginning of the "static int32_t AndroidInputCallback(struct android_app *app, AInputEvent *event)" function, put GestureEvent gestureEvent = { 0 };
And on line 5317, this line was deleted.
Good!
