Building OpenJDK libraries using IcedTea Project for JamVM

Please don't. For one thing, it's completely unnecessary to go chopping bits
out of the Makefile, when you can just update the checksum. For another, if
you just want a CACAO build, all you need is --enable-cacao and the build
will download and use the right zip for you.

Because the build has been done. If you're starting with a different configuration,
you need a new build directory.
