	dynamically linked, set SEC_RELOC for both the .text and .data
	sections.
	(translate_from_native_sym_flags): Don't set BSF_LOCAL for an
	undefined symbol.

7f90aa8b18 Linker now works for go32; other changes keep it from breaking the other
platforms (new backend_data "exec_header_not_counted") (from p3.)

	bfd_default_reloc_type_lookup.

	(coff_compute_file_section_positions): now works out the section
	alignment and size correctly in all cases.
	(coff_get_symtab): looks for contructor symbols and calls the
	right function when they're found. (coff_canonicalize_reloc):
	knows when a section is full of contructors and does the right
	thing.
	* cpu-m88k.c: Added default_reloc_type lookup to the architecture
	description.
	* libbfd-in.h: (bfd_default_reloc_type_lookup) defun  added.
	* libcoff.h: removed #if 0ed code
	* reloc.c: (bfd_reloc_code_real_type) added BFD_RELOC_CTOR for
	arch independent contructtor relocation type.
	(bfd_reloc_type_lookup): removed the comment "this will go away"
	since it won't. (bfd_howto_32): stolen from 88k, this is a 32bit
	reloc which is used when BFD_RELOC_CTOR falls through to give a
	default 32bit reloc for contructors.
	(bfd_default_reloc_type_lookup): added.
	* aoutf1.h: fixed SEGMENT_SIZE typo.

`bfd_reloc_status_type'.  Rename `bfd_reloc_code_enum_real_type'
to `bfd_reloc_code_real_type'.  (This seems to be a misnomer,
it needs a better name.)  All uses changed.
* targets.c:  Rename `enum target_flavour_enum' to `enum
target_flavour', and remove the `_enum' from all of the enum
values themselves.  All uses changed.

* configure.in, config/h-i386mach:  i386 mach host.
* config/t-i386-aout:  Use host-aout.c.
