I have sorted out the syscall-template.S issue by getting the libc6 source.
I have found places saying that the cause of gdb not liking the binary is because of arch incompatibility (32 v 64). I tried this with no change. ~# gdb /usr/bin/Xorg 2>&1 | tee gdb-Xorg.txt GNU gdb (Ubuntu 7.11.1-0ubuntu1~16.04) 7.11.1 Copyright (C) 2016 Free Software Foundation, Inc.
