To provide supporting information, using the i386 release of FreeBSD 10.1:

* ctypes fails to build with the latest from Python 2.7 branch with the message:

    build/temp.freebsd-10.1-RELEASE-i386-2.7-pydebug/usr/home/davin/pycoredev/cpython/Modules/_ctypes/libffi/src/x86/ffi.o: In function `ffi_prep_closure_loc':

    Failed to build these modules:
    _ctypes                                               


* Note that the above failure message was described in issue22521 by @Danya.Alexeyevsky

* ctypes also fails to build with the latest from default/3.5 branch with the very same message


Apparently the compilation failure messages differ between FreeBSD 8.3 and 10.1 (both i386).
