[Android] Define SDL_VIDEO_OPENGL_ES2

Simple DirectMedia Layer for Linux

By default SDL will only link against glibc, the rest of the features will be
enabled dynamically at runtime depending on the available features on the target
system. So, for example if you built SDL with Xinerama support and the target
system does not have the Xinerama libraries installed, it will be disabled
at runtime, and you won't get a missing library error, at least with the 
default configuration parameters.

Build Dependencies
Ubuntu 13.04, all available features enabled:

sudo apt-get install build-essential mercurial make cmake autoconf automake \
libtool libasound2-dev libpulse-dev libaudio-dev libx11-dev libxext-dev \
libxrandr-dev libxcursor-dev libxi-dev libxinerama-dev libxxf86vm-dev \
libxss-dev libgl1-mesa-dev libesd0-dev libdbus-1-dev libudev-dev \
libgles1-mesa-dev libgles2-mesa-dev libegl1-mesa-dev

- This includes all the audio targets except arts, because Ubuntu pulled the 
  artsc0-dev package, but in theory SDL still supports it.
- DirectFB isn't included because the configure script (currently) fails to find
  it at all. You can do "sudo apt-get install libdirectfb-dev" and fix the 
  configure script to include DirectFB support. Send patches.  :)

Joystick does not work

If you compiled or are using a version of SDL with udev support (and you should!)
there's a few issues that may cause SDL to fail to detect your joystick. To
debug this, start by installing the evtest utility. On Ubuntu/Debian:

    sudo apt-get install evtest
Then run:
    sudo evtest
You'll hopefully see your joystick listed along with a name like "/dev/input/eventXX"
Now run:
    cat /dev/input/event/XX

If you get a permission error, you need to set a udev rule to change the mode of
your device (see below)    
Also, try:
    sudo udevadm info --query=all --name=input/eventXX
If you see a line stating ID_INPUT_JOYSTICK=1, great, if you don't see it,
you need to set up an udev rule to force this variable.

A combined rule for the Saitek Pro Flight Rudder Pedals to fix both issues looks 
   SUBSYSTEM=="input", ATTRS{idProduct}=="0763", ATTRS{idVendor}=="06a3", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1"
   SUBSYSTEM=="input", ATTRS{idProduct}=="0764", ATTRS{idVendor}=="06a3", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1"
You can set up similar rules for your device by changing the values listed in
idProduct and idVendor. To obtain these values, try:
    sudo udevadm info -a --name=input/eventXX | grep idVendor
    sudo udevadm info -a --name=input/eventXX | grep idProduct
If multiple values come up for each of these, the one you want is the first one of each.    

On other systems which ship with an older udev (such as CentOS), you may need
to set up a rule such as:
    SUBSYSTEM=="input", ENV{ID_CLASS}=="joystick", ENV{ID_INPUT_JOYSTICK}="1"
