Javac is a Java program  It is distributed as Java bytecode with a
small native-code loader that starts the Java virtual machine.  So,
you don't need to recompile javac.

However, you do need a Java virtual machine that will run on your
new processor.

There is a (rather slow) Java virtual machine written entirely in C++.
You can use that.
