After thinking about this a bit, it looks like ctfmerge is broken.
8.2 ctfmerge running under 8.2 kernel.  Use a bogus argument and
it complains. (So it *is* running before it goes into a coma.)
But with normal arguments it quickly falls asleep.  Thus it is broken.

But... if I run it under gdb, it says program exited normally:

(gdb) run -v -L VERSION -o kernel.debug.verbose cam.o
Starting program: /new/freebsd/tmp/ctfmerge -v -L VERSION -o
 kernel.debug.verbose cam.o

Program exited normally.
(gdb)

And the kernel file shrank from 117MB to 20MB, so it did something.
