The goal of the next dozen of patches is to merge the handling of
suffix rules and per object rules into a single routine and a single
file. Currently there is ext-compile and depen2, and special cases a
bit everywhere dependending on why the case is special. It turns out
everything can be handled uniformly, with a single file.
I tried to do that as smoothly as I could, which explains why there
are so many small (?) patches.
