But that static is needed for GTY marking :).

So the fix is:
```
diff --git a/gcc/config/aarch64/aarch64-builtins.cc
b/gcc/config/aarch64/aarch64-builtins.cc
index 9b23b6b8c33..2bead96cbd6 100644
--- a/gcc/config/aarch64/aarch64-builtins.cc
+++ b/gcc/config/aarch64/aarch64-builtins.cc

 }

 /* Initialize the memory tagging extension (MTE) builtins.  */
-struct
+static GTY(()) struct GTY(())
 {
   tree ftype;
   enum insn_code icode;

```

Will commit in a few minutes.
