have you looked in how much redundancy you have in all these dep ? For LibreOffice, which use one big make to build it all (60k files or so) we wrote a step to combine and de-duplicate all these .d file reducing the amount that need to be parsed by make by quite a bit iow instead of getting a faster process, reduce the amount to be processed.
