I don't like unnecessary dependencies. We have too many of them already,
and it basically means that touching any header file triggers a full
If we go down the path of adding unnecessary dependencies, we might as
well do away with make and just script the damn thing, and that'll
probably be faster since there'll be no dependencies to track. Just
throw everything through ccache and let it deal with anything which
has changed. Just don't allow your disk to fill up during the build,
ccache really doesn't like that.
