[PATCH] build: Add Android.mk script to build wayland libraries as external library of Android

[Marc Chalain]

Hello,
To demonstrate Android on wayland, I attach a picture with weston running
on STE Snowball board (ARM PCU + Mali GPU) current git version with some
specific modifications. Weston uses the framebuffer compositor (fbdev).
Weston is build with Linaro toolchain and the glibc corresponding.
Inside the window, Android Plasma uses JellyBean framework (bionic,
surfaceflinger, ...). SurfaceFlinger is a client of wayland.
Regards,
Marc Chalain.
