[issue21277] don't try to link _ctypes with a ffi_convenience library

[Matthias Klose]

New submission from Matthias Klose:

the ffi_convenience library was once built and installed with oldish GCC versions. Either remove it completely from the search path, or search for  the standard libffi system library.
