I had run a little script once (without DIAGNOSTIC) to create the initial
ISO I used, then for the second test, I edited GENERIC to uncomment the
DIAGNOSTIC flag, and simply reran the following set of commands (in a
script).  It only takes about 15 minutes to finish, I should have done
the "right thing" and just removed the "obj" directory to be sure it was
clean.  I realize the "kernel" line is unecessary as it appears that a
"release" build builds all of the kernels anyway.

  ARCH='vax'
# ARCH='sparc'
# ARCH='alpha'
# ARCH='pmax'

if [ ! -d ~/obj.${ARCH} ]
then
        mkdir ~/obj.${ARCH} || exit 1
fi

cd src || exit 1

./build.sh -j32 -U -u -O ~/obj.${ARCH} -m ${ARCH} tools
./build.sh -j32 -U -u -O ~/obj.${ARCH} -m ${ARCH} kernel=GENERIC
./build.sh -j32 -U -u -O ~/obj.${ARCH} -m ${ARCH} release
./build.sh      -U -u -O ~/obj.${ARCH} -m ${ARCH} iso-image
