 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.
