Mostly ;)

gjdoc classes reside in tools/gjdoc. They end up in their own gjdoc.jar. 
  --with-rt-jar is there to help cross-compiling & bootstrapping. 
--with-gjdoc is there because not everyone may need a javadoc 
implementation. For example, debian ships gjdoc as a its own package.

gjdoc needs libxmlj. That library is currently not built by default, so 
gjdoc should not be built by default either. So cleaning that up was a 
part of the larger gmp-math & awt-implemenations, to only build the java 
libraries that are needed.

I could change it to --enable-gjdoc, if that would make it clearer.
