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

[mchalain [marc.chalain@gmail.com]]

From: mchalain <marc.chalain at gmail.com>

The Wayland directory has to be inside "external" directory of Android tree.
On some old Android bionic version wayland needs an extra support for timerfd_create and signalfd. To pass this problem, I develop a "libglibcpatches" which implement this syscalls. You will can find this library on github repository. But this syscalls exist on the last version of bionic.
The libwayland_client allows to develop a FrameBuffer client for SurfaceFlinger of Android and to run Android over weston or other Wayland server.
The libwayland_server should allows to develop a compositor over SurfaceFlinger, but I never try.
