[dpdk-dev,4/6] fix build error in app/test with gcc4.3
Commit Message
From: Marvin Liu <yong.liu@intel.com>
Build app/test will be failed for function only defined but not used.
test_prefetch.c:65: error: ‘testfn_prefetch_cmd’ defined but not used
Add attribute used in test function declaration can fix this.
static void __attribute__((used)) testfn_##t(void);
