Log Message:
rework how the DEPENDS tree is traversed in the 'clean-depends' target.
now, each branch is only traversed once instead of possibly multiple times.

depending on the size of the DEPENDS list, the speedup is _huge_.  For example
   make clean CLEANDEPENDS=yes
in x11/gnome now takes around 12 minutes instead of 4 hours on a DECstation
5000/240.

Thanks to Hubert for help and suggestions on this.  Look for more changes to
come as this same problem exists in other areas.
