-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.
