Defining _GNU_SOURCE has a large impact on what gets defined when including headers either before or after it. This can result in compile failures if .c file decides to include a standard header file before resctrl.h. It is safer to define _GNU_SOURCE in Makefile so it is always defined regardless of in which order includes are done.
