[Python] Cython compilation error on cython==0.27.3

    Details

      Description

      On the latest master, I'm getting the following error:

      [ 11%] Compiling Cython CXX source for lib...
      
      
      
      Error compiling Cython file:

          return out

      CMakeFiles/lib_pyx.dir/build.make:57: recipe for target 'CMakeFiles/lib_pyx' failed

      With 0.29.0 it is working. This might have been introduced in https://github.com/apache/arrow/commit/12201841212967c78e31b2d2840b55b1707c4e7b but I'm not sure.
