Disable XBIOS driver for mouse and joystick under MiNT. Will write a driver for /dev/mouse later.

 OpenGL driver always uses OSMesa.
 
 (1) GEM does not report relative mouse motion, so xbios mouse driver is used
-to report this type event.
+to report this type event. Under MiNT, using XBIOS mouse driver is not possible.
 
 (2) If you build SDL with threads using the GNU pth library, timers are
 supported via the pth library.
 
+(3) Redirecting XBIOS vectors does not work under MiNT, so it is disabled in
+this case.
