[Mesa-dev] Android build fixes & dropping three automake makefiles

[Emil Velikov]

As usual trying to bring some order and symmetry to the build chaos
that mesa is. Prefixed with a few fixes that make the android build
in gallium a step closer to functional, thus tagged as stable material.

Note: The patches are on top of Giovanni's egl-drm series, so the 
automake (patches 09-12) might not apply cleanly to master.
