Additional (non-autoconf) OpenJDK Options:

  --openjdk-target=TARGET cross-compile with TARGET as target platform

                          (i.e. the one you will run the resulting binary on).

                          Equivalent to --host=TARGET --target=TARGET

                          --build=<current platform>

  --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'.
