android: build libGLES_mesa

This is the first step to integrate Mesa into Android(-x86) build
system.  You can git clone mesa under the external/ directory of Android
source tree and build Android with

 $ make BOARD_GPU_DRIVERS=swrast

It will build libGLES_mesa that will be loaded by Android runtime.

libGLES_mesa is still a stub in this commit.
