tl;dr: The linker produced PLT entries for undefined symbols with
R_X86_64_PLT32 relocations up through Ubuntu 16.04; but produces calls
to empty PLT entries in Ubuntu 18.04. Has this usage ever been legal,
and if so how can it be made to work now?
Since answer is undefined, its behavior is undefined.
Thank you, that is useful information.
