bpo-1294959: Add sys.platlibdir attribute (GH-18381) 

Add --with-platlibdir option to the configure script: name of the
platform-specific library directory, stored in the new sys.platlitdir
attribute. It is used to build the path of platform-specific dynamic
libraries and the path of the standard library.

It is equal to "lib" on most platforms. On Fedora and SuSE, it is
equal to "lib64" on 64-bit systems.

.. data:: platlibdir
Name of the platform-specific library directory. It is used to build the
path of platform-specific dynamic libraries and the path of the standard
library.
It is equal to ``"lib"`` on most platforms. On Fedora and SuSE, it is equal
to ``"lib64"`` on 64-bit platforms which gives the following ``sys.path``
paths (where ``X.Y`` is the Python ``major.minor`` version):
* ``/usr/lib64/pythonX.Y/``:
Standard library (like ``os.py`` of the :mod:`os` module)
* ``/usr/lib64/pythonX.Y/lib-dynload/``:
C extension modules of the standard library (like the :mod:`errno` module,
the exact filename is platform specific)
* ``/usr/lib/pythonX.Y/site-packages`` (always use ``lib``, not
:data:`sys.platlibdir`): Third-party modules
