Alas, that doesn't work. I don't actually need to override the Object
builder, because there's nothing wrong with how it calls g++. What I
need to override is the env.Object() method that tells SCons about
foo.cpp and foo.o in the first place.

That is: I need to sneak an additional dependency into the graph
(early), not interfere with the build itself (late).

So, my original question stands: how do I artificially inject an
additional dependency into the graph for every single *.o file? The
dependency is known early, so there's no reason to try to inject it
late, at build time.
