libstdc++ link errors in support/links-dso-program

Hi.

I attempt to build glibc 2.31 on Debian GNU/Linux 12 Bookworm. It fails at:

Is that because it attempts to link against the system libstdc++, which 
is too new and requires symbols not present in this glibc version? Do I 
need to compile it myself? Or maybe even the whole GCC? I attempted to 
configure it without the SELinux support, but there's still the same 
problem.
