(probably on x86 it all is inlined, but this is not the case for x86_64)
The new code that introduced this issue is in x86_64-only code (signal_x86_64.c).
Thanks for your attempt to fix the problem I created.
I'm not sure why your configure check is in an if statement having to do with the support for CFI directives. Also, the symbol you're checking for (_U_dyn_register) seems suspicious. It's not mentioned in the link errors. Also, I'm not sure it's a reliable export from libunwind. As indicated in the bug report, libunwind does annoying symbol renaming that's not consistent among platforms. (It's definitely not present on OS X, although that's because Apple provides a somewhat customized interface.)
Erich Hoover and I are working on a different approach on the bug. He attached a patch and I attached a counter-proposal patch. I'd appreciate if you could check that mine solves the problem for you.
Thanks, Ken
