*Override host OS dlclose() with a NOP*

Type: ``bool``

Help
====

.. code-block:: none

    Override host OS dlclose() with a NOP.

    This NOP implementation is needed as workaround for a known limitation in
    LSAN (leak sanitizer) that if dlcose is called before performing the leak
    check, "<unknown module>" is reported in the stack traces during the leak
    check and these can not be suppressed, see
    https://github.com/google/sanitizers/issues/89 for more info.
