Re: ELF final_write_processing

[Alan Modra <amodra at gmail dot com>]

I missed some early exits from final_write_processing that mean
_bfd_elf_final_write_processing could be missed.

	* elf-vxworks.c (elf_vxworks_final_write_processing): Don't return
	early.
	* elf32-arc.c (arc_elf_final_write_processing): Likewise.
	* elf32-xtensa.c (elf_xtensa_final_write_processing): Likewise.
