Here's where I am at. I can finish configure but I still have an hack
in generated-configure.sh for freetype. This is my configure script:

cd ~/jdk/jdk8
env -i
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/X11R6/bin:/usr/local/bin:/usr/local/sbin
 \
  CPPFLAGS=-I/usr/local/include \
  LDFLAGS=-L/usr/local/lib \
  sh configure \
  --with-boot-jdk=/home/truk/jdk/j2sdk-image \
  --disable-ccache \
  --disable-freetype-bundling \
  --disable-zip-debug-info \
  --with-cups=/usr/local \
  --with-freetype=/usr/X11R6 \
  --with-freetype-include=/usr/X11R6/include/freetype2 \
  --with-giflib=system \
  --with-jobs=16 \
  --with-zlib=system \
  2>&1 | tee -a ~/jdk/build-jdk8.log

Attached is the diff I'm running with that has a hack for freetype
in it. It needs more work to match correctly with versioned shared
libs that OpenBSD has.
