How do you work that out? I did explicitly NOT make a distinction between 
bytecode compilers and machine code compilers: indeed GCJ can generate 
both. Pretty much at the start of all this, I said two things:

1) that you can define a high-level 'compiled language' as one where
   a program, usually known as a 'compiler', must be used to translate
   the human readable source code into something more computer friendly
   before it can be run and that an interpreted language does not have
   an explicit compilation step.

2) that compilers or assemblers that can directly generate executable
   code without the aid of a linker are rare in my experience and that I
   knew three cases (6800 assemblers, PL/9 and Elliott 503 Algol) of
   compiled languages that don't use a linker in the sense of a 
   post-processor for compiler output. 

   I should have included Java in this list since it too lacks an
   explicit linkage stage that must be completed before attempting to
   run the compiled code: my mistake. I suppose any system that can run
   relocatable binary code can let the runtime loader handle fixing up
   inter-module links. The JVM's loader does this and IIRC so
   do the loaders used by IBM's OS/400 and ICL's VME/B   

I have always heard the phrase 'interpreted languages' used to describe 
the case where source code is apparently executed directly without any 
explicit compilation stage. Examples are Perl, awk and command-line 
interpreters, e.g. bash or command.exe
