It assigned libraries for multiprocessing module according
the host_platform, but not pass it to Extension.
In glibc, the following commit caused two definition of
sem_getvalue are different.
https://sourceware.org/git/?p=glibc.git;a=commit;h=042e1521c794a945edc43b5bfa7e69ad70420524
(see diff in nptl/sem_getvalue.c for detail)
`__new_sem_getvalue' is the latest sem_getvalue@@GLIBC_2.1
and `__old_sem_getvalue' is to compat the old version
sem_getvalue@GLIBC_2.0.
If not explicitly link to library pthread (-lpthread), it will
load glibc's sem_getvalue randomly at runtime.
Such as build python on linux x86_64 host and run the python
on linux x86_32 target. If not link library pthread, it caused
multiprocessing bounded semaphore could not work correctly.
...
>>> import multiprocessing
>>> pool_sema = multiprocessing.BoundedSemaphore(value=1)
>>> pool_sema.acquire()
True
>>> pool_sema.release()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: semaphore or lock released too many times
...
And the semaphore issue also caused multiprocessing.Queue().put() hung.

When py3 applications are exiting we often see errors similar to the
following:
Exception ignored in: <function WeakValueDictionary.__init__.<locals>.remove at 0x7fcb56b09400>
Traceback (most recent call last):
File "/usr/lib64/python3.5/weakref.py", line 117, in remove
TypeError: 'NoneType' object is not callable
After a quick search this was found to be a well reported issue
upstream and had an appropriate fix which is backported here.

Porting patch from
<409482251b>
to use _sysconfigdata.py to initialize distutils.sysconfig.
This patch makes that distutils.sysconfig doesn't need config-*/Makefile
in libdir any more. Next we can move it from python3-misc to python3-dev
package.

Prior versions of python do not support openssl 1.1; updating to
Python 3.6 on the other hand is a lot more involved, and so should
be done by a specialist/maintainer.
