PATCH 1/1 python: fix the _ctype module compiling error caused by ffi library

The ctype compiling error for python 2 is caused by the mixed ifdefs X86_WIN32 and X86_WIN64. The issue is tracked by python upstream issue https://bugs.python.org/issue23042.
Whereas the patch is not completely applied on python package. This additional patch is a supplement for the issue.
