I think I will ping pynac upstream to see if they have any idea but I think
it may be a recurring gcc or a subtle abuse of C++. It would be interesting to see
if putting -fno-fat-lto-objects would with getting the symbol in pynac. There are
other things ‘i can think off that may work but need to consult upstream and
people who know more c++.

I added after the first couple of packages (like pciutils, elfutils, openssh, etc.) wouldn't build to see if it would help so I didn't have to use the "no-lto" environment setting from that graphite and lto instruction page I referenced earlier. It didn't see to work as I now have a package.env file full of no-lto entries. Neither sage nor pynac are no-lto entries right now as it appeared to me that they merged.
