More fixes related to NONE relocs

	* elf32-bfin.c (bfin_bfd_reloc_type_lookup): Correct loop iteration
	to allow return of first howto.
	* elf32-fr30.c (fr30_reloc_type_lookup): Likewise.
	* elf32-m32c.c (m32c_reloc_type_lookup): Likewise.
	* elf32-moxie.c (moxie_reloc_type_lookup): Likewise.
	* elf32-or1k.c (or1k_reloc_type_lookup): Likewise.
	* elf32-rl78.c (rl78_reloc_type_lookup): Likewise.
	* elf32-rx.c (rx_reloc_type_lookup): Likewise.
	* elf32-tilepro.c (tilepro_reloc_type_lookup): Likewise.
	* elf32-xstormy16.c (xstormy16_reloc_type_lookup): Likewise.
	* elfxx-tilegx.c (tilegx_reloc_type_lookup): Likewise.
	* elf32-nios2.c (nios2_reloc_map): Add mapping for R_NIOS2_NONE.
	* elf32-spu.c (spu_elf_bfd_to_reloc_type): Allow return of R_SPU_NONE.
	(spu_elf_reloc_type_lookup): Adjust to suit.
