The i386-netbsd and i386-netbsdelf targets are now equivalent, as far
as configury is concerned.  The following merges them.

BTW, someone is going to have to step up and fix the i386-openbsd*
target, since the NetBSD code no longer really works for it (and this
is likely to be even more true in the not-distant future, when all of
the NetBSD thread code gets merged in to GDB).

Committed to trunk:

	* configure.tgt (i[3456]86-*-netbsdelf*): Merge with...
	(i[3456]86-*-netbsd*): ...this.  Set gdb_target to nbsd.
	(i[3456]86-*-openbsd*): Make this a separate entry.  Add a
	comment noting that this needs its own target configuration.
	* config/i386/nbsd.mt: New file.
	* config/i386/nbsdaout.mt: Remove.
	* config/i386/nbsdelf.mt: Ditto.
	* config/i386/tm-nbsdaout.h: Ditto.
