It was an intentional design decision not to enable `-fptrauth-elf-got` as part of pauthtest ABI on public LLVM upstream. Most platforms use RELRO, and we do not need GOT signing for them because the GOT section becomes read-only right after dynamic relocations are resolved.

So, unless @asl has a different vision on this, I suppose it's worth leaving this choice for downstream platforms :)
