I found _exactly_ this problem about 24 hours ago, when trying a "-j16" on
an machine with 4.4-RC4 installed from CD, and then updated via CVSup. I
don't know if it was casual or not, but I did a "make cleandir" on
/usr/src (and wiped out the remains in /usr/obj), and then the "make -j16
world" went smoothly.

  Cheers,
  JMA
