use Config '%Config';
print $Config{ usethreads };

A conceptual problem with your question may be that you think that only certain version numbers of Perl come threaded or unthreaded. This is a misconception. Perl can be built with or without threads in any version number starting since 5.6 (or even earlier). Whether you have threads available depends on the person who built your Perl binary and whether they enabled that option or not.
