If anyone has any objections, please let me know. ------------------ From: Ilpo Järvinen [ Upstream commit 3a1e4a91aa454a1c589a9824d54179fdbfccde45 ] _GNU_SOURCE is defined in resctrl.h. 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.
