+    aarch64: simplify the DT_AARCH64_VARIANT_PCS handling code
+    
+    Remove unnecessary variant_pcs field: the dynamic tag can be checked
+    directly.
+    
+            * sysdeps/aarch64/dl-machine.h (elf_machine_runtime_setup): Remove the
+            DT_AARCH64_VARIANT_PCS check.
+            (elf_machine_lazy_rel): Use l_info[DT_AARCH64 (VARIANT_PCS)].
+            * sysdeps/aarch64/linkmap.h (struct link_map_machine): Remove
+            variant_pcs.
