265 Additional (non-autoconf) OpenJDK Options:
266 --openjdk-target=TARGET cross-compile with TARGET as target platform
267 (i.e. the one you will run the resulting binary on).
268 Equivalent to --host=TARGET --target=TARGET
269 --build=<current platform>
270 --debug-configure Run the configure script with additional debug
271 logging enabled.
272
273 Please be aware that, when cross-compiling, the OpenJDK configure script will
274 generally use 'target' where autoconf traditionally uses 'host'.
275
276 Also note that variables must be passed on the command line. Variables in the
277 environment will generally be ignored, unlike traditional autoconf scripts.
