What has the glibc version got to do with anything?

If it's not present on the old system that means you're not using the
libstdc++.so from GCC 7.4.0, which you're required to do. You can't compile
with a new GCC and then use an old libstdc++.so at runtime. That's always been
true. Defining _GLIBCXX_USE_CXX11_ABI has nothing to do with that.
