[AD] Linux joystick driver button limitation

[Tom Fjellstrom <tfjellstrom@xxxxxxxxxx>]

I have a USB SideWinder GamePad Pro and allegro
has always ignored the 9th button, so i took
a look at ljoy.c and changed the 'if(num_buttons > 8)...'
to 'if(num_buttons > 9)...', and also the line
in joy_poll so now I have a working 9th button
and want to know if this change would affect
other joysticks? (i.e.: gameport joysticks)

If no one has a problem with this change, I've
included a small diff file which should be applied
in the src/linux directory.
