because this config was focused more on building VM binary without
linkage to OpenGL libs,
so you can start VM without GL libs installed in your system.
And  B3DAcceleratorPlugin is built as external module, and there is no
restrictions on it.

To avoid building it, you need to just exclude it from build, like:

| conf |
conf := CogUnixNoGLConfig new.
conf externalPlugins: (conf externalPlugins copyWithout:
#B3DAcceleratorPlugin ).
conf generateSources;generate

but there are some other things needs to be updated, like
#addDriver: sources:generator: method which now don't needs to be
overridden in subclass,
because it can only change #linkFlags
