The makefile completes sucessfully when tested on an Ubuntu 18 machine with much fewer warnings, and fails on Ubuntu 20. My linux kernel for Ubuntu 18 is 4.15.0-109-generic while Ubuntu 20 is 5.4.0-40-generic. I believe this issue applies for any version >= 5.2, where in sys/socket.h, SIOCGSTAMP is now SIOCGSTAMP_OLD.
