Ah, ok.  Yes, that makes sense.  Should ``Porting GDB'' be moved to 
before the host, architecture and target sections (and add a native 
section?).  That way the user is lead into the other chapters.  Porting 
GDB being a brief overview.

Yes.  Good point.  ``host only'' is a backward way of saying a GDB 
supporting a ``non native target''.  More to rewrite.
