 Wouldn't python3 be always available in any case as a symlink to some
python3.N version? This seems to be the case at least under Debian.

 If we do need to test for all the versions perhaps it would be worth it to
at least do it in a loop, i.e. something like

	for py_ver in 3.4 3.3 3.2 3.1 3.0 3; do
		AC_CHECK_PROGS(PYTHON3, [python$py_ver])
		if test -n "$PYTHON3"; then
			AC_CHECK_PROGS(PY3CONFIG, [python$py_ver-config]);
			if test -n "$PY3CONFIG"; then
				break
			fi
		fi
	done

?
