This is a compile check, whole test should be wrapped with #ifdef and fallback
using TST_TEST_TCONF() macro.

#include "config.h"
#include "tst_test.h"
...
#ifdef HAVE_DECL_MREMAP_DONTUNMAP
// other includes

#else
TST_TEST_TCONF("Missing MREMAP_DONTUNMAP in <linux/mman.h>");
#endif

This quits tests early.
And please use #ifdef.

Kind regards,
Petr
