Not sure if it is of any help but mod_python seems to be using this
configure.in snippet to detect (and reject) a threaded python installation:

# check if python is compiled with threads
AC_MSG_CHECKING(whether Python is compiled with thread support)
PyTHREADS=`$PYTHON_BIN -c "import sys; print \"thread\" in
sys.builtin_module_names"`
if test "$PyTHREADS" = "1"; then
AC_MSG_RESULT(yes)
echo
echo " ****** WARNING ******"
echo " Python is compiled with thread support. Apache 1.3 does not
use threads."
echo " On some systems this will cause problems during compilation,
on others "
echo " it may result in unpredictable behaviour of your Apache
server. Yet on"
echo " others it will work just fine. The recommended approach is to
compile"
echo " Python without thread support in a separate location and
specify it with"
echo " --with-python option to this ./configure script."
echo
else
AC_MSG_RESULT([no threads, good])
