(_dl_tlsdesc_resolve_rela): Likewise.
(_dl_tlsdesc_resolve_hold): Likewise.
(_dl_tlsdesc_undefweak): Remove ldar.
(_dl_tlsdesc_dynamic): Likewise.
* sysdeps/aarch64/dl-tlsdesc.h (_dl_tlsdesc_return_lazy): Remove.
(_dl_tlsdesc_resolve_rela): Likewise.
(_dl_tlsdesc_resolve_hold): Likewise.
* sysdeps/aarch64/tlsdesc.c (_dl_tlsdesc_resolve_rela_fixup): Remove.
