* nlm32-i386.c: New file. First cut at i386 NLM code.

	* nlm32-i386.c: New file.  First cut at i386 NLM code.
	* libnlm.h: Added some more prototypes.
	(struct nlm_relent): New structure.
	(nlmNAME(symbol_type)): Added rcnt and relocs fields.
	(struct nlm_obj_tdata): Added new fields: nlm_symbols,
	nlm_text_low, nlm_data_low, nlm_reloc_fixups,
	nlm_reloc_fixup_secs.
	(struct nlm_backend_data): New structure, with accessor macros.
	* nlmcode.h: Use NLM_HIBIT rather than MSB.
	(nlm_object_p): Set SEC_RELOC for .text and .data.  Don't set
	SEC_DATA for .bss.  Set HAS_RELOC and HAS_SYMS for abfd.  Set the
	architecture.
	(nlm_swap_fixed_header_out, nlm_swap_variable_header_out,
	find_nonzero, nlm_swap_auxiliary_headers_out): New outbound
	swapping functions.
	(nlm_get_symtab_upper_bound, nlm_slurp_symbol_table): Include
	external references in symbol table as undefined symbols.
	(nlm_get_symtab, nlm_slurp_symbol_table): Fill in alocation
	argument in get_symtab rather than in slurp_symbol_table.
	(nlm_slurp_symbol_table): Save symbol information in tdata.
	(nlm_print_symbol): New function.
	(nlm_slurp_reloc_fixups, nlm_get_reloc_upper_bound,
	nlm_canonicalize_reloc): New functions to read relocs.
	(nlm_compute_section_file_positions, nlm_set_section_contents,
	nlm_external_reloc_compare, nlm_write_object_contents): New
	functions to create NLM files.
	* nlm-target.h: Define all the nlm functions here either as
	default values or in terms of nlmNAME.  Use JUMP_TABLE(nlm).  Set
	the backend_data field to TARGET_BACKEND_DATA.
	* nlm32-gen.c, nlm64-gen.c: Don't define function macros here;
	they are now in nlm-target.h.
	(TARGET_BACKEND_DATA): Define as NULL.
	* nlm.c (nlm_mkobject): Do allocate the tdata field.
	(nlm_set_arch_mach): New function.
	* targets.c: Added nlm32_i386_vec.
	* Makefile.in (BFD32_BACKENDS): Added nlm32-i386.o.
	(CFILES): Added nlm32-i386.c.
	(nlm32-gen.o, nlm64-gen.o): Depend on nlm-target.h.
