Fixes fails on SH and NDS32 introduced by dyn_reloc tidy.

	* elf32-lm32.c (lm32_elf_check_relocs): Skip non-ALLOC sections.
	* elf32-m32r.c (m32r_elf_check_relocs): Likewise.
	* elf32-nds32.c (nds32_elf_check_relocs): Likewise.
	* elf32-or1k.c (or1k_elf_check_relocs): Likewise.
	* elf32-sh.c (sh_elf_check_relocs): Likewise.
