* elf32-spu.c (mark_functions_via_relocs): Don't assume that 

the "->start" pointer reaches to function origin, so that we
	can handle functions split over more than two sections.
	(build_call_tree): Likewise.
	(pasted_function): Don't attempt to set fun->start back to the
	function origin, just go back one section.
