    --debug-configure       Run the configure script with additional debug
                            logging enabled.
  
  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.
