trying to set up my build systems for a clean build of the whole tree today
(after the 04:30 PDT tree commit), and I ran "make cleandir" in /usr/src on
the sparc. And make died. I built a debug-symbol version of make, and got
this after death again:

[...]

It's late and I'm just a touch tired to deal with this now, but I toss this
out to you all in case someone might want to take a poke at it before I
wake up again.
