- Disable Jikes to avoid trouble with JDK 1.3

- Disable building extra documentation when not using JDK 1.5 as the Xalan
  processor used to tranform the XML source files seems to try and use X11
  (which fails if built by superuser in a console) [1]

NOTE: When using JDK 1.5 (java/jdk15) this error does not occur so it seems
like we could find a fix for that. Otherwise I will probably convert the port
to a binary one.
