I threw -ENOSYS in mostly as a sanity check.  If the suite is meant to be
portable to other POSIX systems, you'll certainly want to do something
else if gettid() doesn't exist, since it's linux-specific.  The only aim
of the patch was to shoot for portability accross all Linux platforms
(many of which don't have _syscall magic macros, and word on the street is
that we may not have them on any arches in the future).
