Well, it's Java -- just compile on another architecture and copy the
class files. JNI headers also will look the same on all Linux
architectures.

The tools are still written in Java:

Just copy tools.jar from some 1.3.1 J2SDK and run "java -classpath
/path/to/tools.jar:. com.sun.tools.javac.Main ..." instead of javac
and "java -classpath /path/to/tools.jar:. com.sun.tools.javah.Main
..." instead of javah.
