Can't pass endian argument to p_uint64.from_str

It looks like the MetaPackable's from_str method accepts an _endian_ keyword argument:

#!python
def from_str(cls, s, **kw):
        endian = kw.get('_endian_', cls._endian_)
        return cls.from_tuple(struct.unpack(endian + cls._format_, s), **kw)

However it doesn't actually work:

#!python
macholib.ptypes.p_uint64.from_str('\x01\x00\x00\x00\x00\x00\x00\x00', _endian_='<')

Here is the exception I get from iPython:

TypeError                                 Traceback (most recent call last)

---> 67         return cls.from_tuple(struct.unpack(endian + cls._format_, s), **kw)

I'm reopening this issue because the patch breaks py2app.
