+Subject: [PATCH] meson: unify linux/stat.h check with other checks and use
+ _GNU_SOURCE
+
+Using _GNU_SOURCE is better because that's how we include the headers in the
+actual build, and some headers define different stuff when it is defined.
+sys/stat.h for example defines 'struct statx' conditionally.
