I've been continuing the work to execute a full build followed by a
partial build. However, I think I'm still blocked by an <insert
obvious missing env VAR> issue.

Full Build:
----------------
I set the following env vars

export LANG=C
export ALT_BOOTDIR=/usr/lib/jvm/java-7-openjdk-amd64

I execute a full build of the cloned code base from
http://hg.openjdk.java.net/jdk8/tl (after get_sources.sh is run) and
that all works fine

Partial Build:
----------------

# Create a backup of the full build (as per Weijun's recommendation)
cp -R /home/openjdk/projects/jdk8_tl/build/linux-amd64
/home/openjdk/projects/jdk8_tl/build/linux-amd64_backup

# Set the ALT_JDK_IMPORT_PATH to point to the j2sk-image backup of the
full build
export ALT_JDK_IMPORT_PATH=/home/openjdk/projects/jdk8_tl/build/linux-amd64_backup/j2sdk-image

# Run the warnings build
make JAVAC_MAX_WARNINGS=true JAVAC_WARNINGS_FATAL=
OTHER_JAVACFLAGS="-Xmaxwarns 10000" &> build.log

It builds up to a point, but then has the problem where it's looking
for due to directory structure issues (it's looking too far back up
the directory tree basically).

--------------------

/bin/mkdir -p ../../../../build/linux-amd64/tmp/sun/sun.security.ec/unsigned
rm -f ../../../../build/linux-amd64/tmp/sun/sun.security.ec/unsigned/sunec.jar

Apart from ALT_JDK_IMPORT_PATH are there any other env vars I need to
set in order to have a partial build run (using the full build as a
base)?
