python2.2 -c "import sys;print 'thread' in sys.builtin_module_names"

or

python2.2 -c "import sys;sys.exit('thread' not in sys.builtin_module_names)"

depending on wether stdout or an exit value is more convenient.
Note the latter verson inverts the value to be compatible with
/bin/{true,false}'s inverted return values.
