* targets.c (bfd_target): Added relocateable argument to
	_bfd_get_relocated_section_contents.  Added _bfd_seclet_link
	target vector for linker use.
	* bfd.c (bfd_seclet_link): New macro.
	* bfd-in.h (JUMP_TABLE): Added _bfd_seclet_link.
	* seclet.c (rel, seclet_dump_seclet): Added relocateable argument
	and boolean return value.  Made static.
	(bfd_generic_seclet_link): Renamed from seclet_dump.  Added
	relocateable argument.
	* reloc.c (bfd_generic_get_relocated_section_contents): Added
	relocateable argument (if relocateable, saves relocs).
	* bout.c (b_out_get_relocated_section_contents),
	reloc16.c (bfd_coff_reloc16_get_relocated_section_contents): Added
	relocateable argument (if relocateable, just calls
	bfd_generic_get_relocated_section_contents).
	* libcoff-in.h (bfd_coff_reloc16_get_value): Added relocateable
	argument to prototype.
	* All targets: Set new _bfd_seclet_link vector to
	bfd_generic_seclet_link.

INTERNAL_FUNCTION
bfd_generic_seclet_link
SYNOPSIS
boolean bfd_generic_seclet_link
(bfd *abfd,
PTR data,
boolean relocateable);
DESCRIPTION
The generic seclet linking routine. The caller should have
set up seclets for all the output sections. The DATA argument
should point to a memory area large enough to hold the largest
section. This function looks through the seclets and moves
the contents into the output sections. If RELOCATEABLE is
true, the orelocation fields of the output sections must
already be initialized.
