Declare Gould configuration obsolete:

* configure.host, configure.tgt: Comment out Gould configs.
	* Makefile.in: Comment out Gould-related actions.
	* gould-xdep.c, gould-tdep.c, config/gould/*: Comment out.
	* NEWS: Mention obsolete status.
And the first one bites the dust...

* OBSOLETE configurations
Gould PowerNode, NP1 np1-*-*, pn-*-*
Configurations that have been declared obsolete will be commented out,
but the code will be left in place. If there is no activity to revive
these configurations before the next release of GDB, the sources will
be permanently REMOVED.
* Readline 2.2
GDB now uses readline 2.2.
