meta-openembedded and poky: subtree updates
Squash of the following due to dependencies among them
and OpenBMC changes:
meta-openembedded: subtree update:d0748372d2..9201611135
meta-openembedded: subtree update:9201611135..17fd382f34
poky: subtree update:9052e5b32a..2e11d97b6c
poky: subtree update:2e11d97b6c..a8544811d7
The change log was too large for the jenkins plugin
to handle therefore it has been removed. Here is
the first and last commit of each subtree:
meta-openembedded:d0748372d2
cppzmq: bump to version 4.6.0
meta-openembedded:17fd382f34
mpv: Remove X11 dependency
poky:9052e5b32a
package_ipk: Remove pointless comment to trigger rebuild

+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.
