Subject: [PATCH] examples: Define _GNU_SOURCE for more examples
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some of our examples use GNU/Linux extensions functions/variables:

1) domtop.c uses usleep(3),
2) logging.c uses getopt(3).

Put _GNU_SOURCE definition at the top of corresponding files so
that users can just grab the code and compile it (in contrast
with the rest of the code where _GNU_SOURCE is declared in
meson-config.h).
