ARC: ldso: don't use _DYNAMIC@gotpc construct #1
This converts elf_machine_dynamic() to not use the _DYNAMIC@xx construct which was historically converted by assembler into _GLOBAL_OFFSET_TABLE Now that "hack" is being removed from assembler, we need to make sure that no code relies on that magic "conversion".
