It's a bug that affects only libstdc++ in dynamic linking, static works. Also `std::call_once` libc++ works.

Dropping a platform for little reason isn't reasonable. Maybe we can prepare a CMake test detecting if it works, if so than enable it. After that libstc++ on NetBSD won't be holding back others.
