Fix bug when generating REL type relocs for assembler generated build notes.

	PR 24748
	* write.c (create_note_reloc): Add desc2_offset parameter.  Change
	name of offset parameter to note_offset.  Only use desc2_offset
	when placing addend into REL reloc's address space.
	(maybe_generate_build_notes): Update parameters passed to
	create_note_reloc.
