    configure of the cross compilation is run with '--enable-shared --with-pydebug'.

    The cross-compilation fails attempting to link the extension module objects with a non existing libpython3.6m instead of libpython3.6dm, when the native python that is used to run setup.py had not been configured with --with-pydebug.

    The attached patch fixes this problem.

    Another description of the problem:

    • On the build system, the native python (in one of the search directories of PATH) has been built without --with-pydebug.
    • The cross-compilation is done on this build system with --with-pydebug.
    • The cross-compilation of all the Python extension modules fails with:
      /bin/ld: error: cannot find -lpython3.6m
      collect2: error: ld returned 1 exit status
