Rene,

I'm reviewing your changes now; they look good!
Please also give me a patch for the build system documentation.
I want to know how to use your new features! ;-)

Also, <suppress>true seems like a fine approach, but it should not be
specific to the lib rule; the logic for it should go in
declare-local-targets.
