+Here is a patch for the first possibility.
+It certainly makes libstdc++.so to link and even the unwind info looks
+good on brief skimming.

+
+	* config/tc-ia64.c (start_unwind_section): Add linkonce_empty
+	argument, don't do anything if current section is not
+	.gnu.linkonce.t.* and linkonce_empty is set.
+	(generate_unwind_image, dot_endp): Adjust callers, call
+	start_unwind_section (*, 1) if nothing will be put into the
+	section.
