When building python33, the following test failure happens on ppc64le:

======================================================================
FAIL: test_memoryview_struct_module (test.test_buffer.TestBufferProtocol)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/builddir/build/BUILD/Python-3.3.7/Lib/test/test_buffer.py", line 2506, in test_memoryview_struct_module
    self.assertEqual(m[1], nd[1])
AssertionError: -21.099998474121094 != -21.100000381469727
----------------------------------------------------------------------


This tests equivalence of struct.pack_into and assigning into a memoryview, and fails on a Decimal instance.

This doesn't look too serious, so I'll disable the test for now, but it would be nice to look into it some day.

(Given the nature of the package and the arch specificity of this test failure, I'm not sure it's worth it.)
