* elf32-xtensa.c (is_same_value): Add final_static_link argument and
require relocations against a weak symbol to reference the same symbol hash entry if not a final, static link. (get_cached_value, add_value_map): Add final_static_link argument. (remove_literals): Pass final_static_link argument as needed.
