* hpux-core.c: New file; backend for HP/UX style core files.

Browse source 
* bfd.c (struct _bfd): Renamed hppa_core_data field to
	hpux_core_data.
	* bfd-in2.h: Updated.
	* hppa.c (make_bfd_asection, hppa_core_file_p,
	hppa_core_file_failing_command, hppa_core_file_failing_signal,
	hppa_core_file_matches_executable_p): Moved into hpux-core.c.
	Removed from target vector.
	* libhppa.h (struct hppa_core_struct and accessor macros): Moved
	into hpux-core.c.
	* targets.c: If HPUX_CORE is defined, add hpux_core_vec to
	target list.
	* config/hp300.mh (HDEFINES): Set to -DHPUX_CORE.
	(HDEPFILES): Set to hpux-core.o.
	* config/hppabsd.mh, config/hppahpux.mh: Likewise.
	* hosts/hp300.h (HOST_HP300HPUX): Define.
	* Makefile.in (OPTIONAL_BACKENDS): Added sco-core.o,
	aix386-core.o, hpux-core.o.
	(sco-core.o, aix386-core.o, hpux-core.o): New dependencies.
