* Makefile.in: Add stuff to build nlmstub.

Browse Source 
* Add rule for annotate.o to keep Sun make happy.
	* configure.in:  Add config for powerpc/Netware.

	* partial-stab.h (near N_SO):  Don't call START_PSYMTAB with null
	filename.  This speeds up handling of trailing N_SO stabs (they
	mark the end of a .o file).

	* target.c, target.h:  Change the way pushing and popping of
	targets work to support target overlays and inheritance.
	* corelow.c, hppa-tdep.c, inflow.c, remote-nindy.c, utils.c:
	Fixup references to current_target, due to previous changes.

	* config/i386/tm-i386nw.h:  Enable longjmp support.  More work is
	needed to get the address of longjmp out of the target.
