 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.
