All the Java compilers are written in Java (ecj & javac). So to run them, you
need a JVM and its class library.

It's those binary files which allow gcj to bootstrap the stack. If OpenJDK
had a minimal binary class library, it would be able to bootstrap itself.

But, as things stand, you need enough of the JDK to run a Java compiler
and build the OpenJDK class libraries. GCJ currently fulfils that need
where there isn't already an OpenJDK installation available.
