Additional (non-autoconf) OpenJDK Options:

Please be aware that, when cross-compiling, the OpenJDK configure script will
generally use 'target' where autoconf traditionally uses 'host'.
Also note that variables must be passed on the command line. Variables in the
environment will generally be ignored, unlike traditional autoconf scripts.
