--- Comment #1 from Hannes Domani <ssbssa at sourceware dot org> ---
I think it should be as simple as that:

--- a/gdb/linux-tdep.c
+++ b/gdb/linux-tdep.c
@@ -350,6 +350,13 @@ linux_get_siginfo_type_with_fields (struct gdbarch
*gdbarch,
   append_composite_type_field (type, "si_fd", int_type);
   append_composite_type_field (sifields_type, "_sigpoll", type);

+  /* _sigsys */
+  type =3D arch_composite_type (gdbarch, NULL, TYPE_CODE_STRUCT);

   siginfo_type =3D arch_composite_type (gdbarch, NULL, TYPE_CODE_STRUCT);
   TYPE_NAME (siginfo_type) =3D xstrdup ("siginfo");

But I don't have Linux, so I can't test it.
