Building MLVM version of OpenJDK (Java 1.7) on Mac OS X

Take a look at the comments and code in update.sh.

I use update-usr-local.sh after a successful build to copy the new JVM into /usr/local.

I add pickjdk.sh into my ~/.bash_profile to allow easy switching between multiple JVMs.

I use create_tarball.sh to make a copy of the build to share.
