* elf32-mips.c (mips_elf_check_relocs): Create the .rel.dyn

	* elf32-mips.c (mips_elf_check_relocs): Create the .rel.dyn
	section if it might be needed, not just if info->shared.
	(mips_elf_adjust_dynamic_symbol): Make room for a null element at
	the start of .rel.dyn if we are going to use it.
	(mips_elf_finish_dynamic_sections): Only clear the first element
	of .rel.dyn if the size is greater than zero.
Fix this case from c-torture:
extern int abort();
typedef int (*frob)();
frob f[] = {abort};
main()
{
  exit(0);
}
