But it works, doesn't it?  That you cannot transfer the binary to some
random system is because the compiler checks the features to use (like
GNU unique symbols) when building GCC.

That means it's a dependency on the dynamic linker of the system, not
on libstdc++.  Your program can end up using GNU unique symbols, too,
which would then result in exactly the same issue.
