So these seem to fall into the "people wanting to consume GTK3 outside
of the GNOME schedule".  We should be receptive to this, but we also
shouldn't block progress in GNOME on it.

Anyways there are two options:
1) Make linking to at-spi2-atk a build-time option, this is related
   to simply unbreaking the OS X/Win32 build as below.
2) Providing an API for gtk3 users to disable it programatically.  I
   guess the environment variable is an attempt to do this, but the
   problem with that is that by default it propagates to child
   processes, so if e.g. Firefox launches another application to
   handle a download, the application will "mysteriously" have
   a11y disabled.

That's an easy fix really.
