app_python: fix compiler warning

>    Add "-fno-strict-aliasing" to compilation flags
>
>    Fixes a slew of:
>      "dereferencing type-punned pointer will break strict-aliasing rules"
>    warnings from GCC for lines of the form:
>      Py_INCREF(Py_True);
>    and
>      Py_INCREF(Py_False);
>
>    due to the cast from PyIntObject* to PyObject*
>
>    GCC is technically correct here; see:
>      http://www.python.org/dev/peps/pep-3123/
>    though this is unlikely to lead to non-working machine code.
