The problem here is not that it's requiring X, but that it's requiring OpenGL, 
since you almost certainly still have opengl in DISTRO_FEATURES. The 
dependency chain is:

libav -> virtual/sdl (libsdl) -> libglu [if opengl is in DISTRO_FEATURES]

Just add opengl to your DISTRO_FEATURES_remove value and it should build 
without trying to build libglu.

Cheers,
Paul
