Get the new COFF linker code working for i386-lynx.

	* cf-i386lynx.c: Remove #if 0 code.
	(i386_lynxos_coff_object_p): Remove unused function.
	(coff_bfd_link_add_symbols): Define.
	(lynx_link_add_symbols): New static function.
	* coffcode.h (coff_bfd_link_hash_table_create): If
	coff_relocate_section is defined, only define this if not already
	defined.
	(coff_bfd_link_add_symbols, coff_bfd_final_link): Likewise.

	* linker.c (_bfd_generic_final_link): Handle
	bfd_indirect_link_order explicitly, rather than via
	_bfd_default_link_order.
	(set_symbol_from_hash): New static function, broken out of
	_bfd_generic_link_write_global_symbol.
	(_bfd_generic_link_write_global_symbol): Symbol setting code moved
	to set_symbol_from_hash; call it.
	(default_indirect_link_order): Add generic_linker argument.
	Change all callers.  If false, set the generic symbols based on
	the hash table entries.
