[dpdk-dev] [PATCH 09/15] app/test: fix setting of -D_GNU_SOURCE with meson

[Natanael Copa]

in app/test/meson.build the default_cflag is never used so the
-D_GNU_SOURCE was never passed as intended.

Fixes the following build error with musl libc:

../lib/librte_eal/common/include/rte_lcore.h:26:9: error: unknown type name 'cpu_set_t'
 typedef cpu_set_t rte_cpuset_t;
         ^~~~~~~~~

The problem is that cpu_set_t is only defined when _GNU_SOURCE is set.
