Alex Smith 3fed1a15f5 Get app_server working on x86_64. 
With this commit, app_server now compiles and runs at boot! Nothing
particularly interesting happens, just the blue background and a mouse
pointer. Remote backends are broken and not compiled in, see #8834.
Note that it won't be possible to build this quite yet, need to get
the FreeType package uploaded.
