python3: drop unneeded multiprocessing module patch
pthread has been merged into the main libc library (and was never separate in musl), so separate linking for it is no longer needed. I ran the reproducing sequence on qemux86, qemux86_64 and same targets with musl, and it went fine: root@qemux86:~# python3 Python 3.10.0 (default, Oct 4 2021, 17:55:55) [GCC 11.2.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import multiprocessing >>> pool_sema = multiprocessing.BoundedSemaphore(value=1) >>> pool_sema.acquire() True >>> pool_sema.release() >>> Signed-off-by: Alexander Kanavin <alex@linutronix.de> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

-Subject: [PATCH] setup.py: pass missing libraries to Extension for
- multiprocessing module
-
-In the following commit:
-...
-commit e711cafab13efc9c1fe6c5cd75826401445eb585
-Author: Benjamin Peterson <benjamin@python.org>

-...
-(see diff in setup.py)
-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.
-
-To build python for embedded Linux systems:
-http://www.yoctoproject.org/docs/2.3.1/yocto-project-qs/yocto-project-qs.html
-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.
