description:
Allow the test to build on systems where sys/mman.h does not provide
PROT_MPROTECT(), or if the test is built without _NETBSD_SOURCE defined,
by providing a dummy #define if the real one does not exist.  The test
might then fail, if the PROT_MPROTECT() is really needed, but that's
better than not building.
