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
poky:a8544811d7
pbzip2: Fix license warning

+Subject: [PATCH] cmake: Add check for atomic support
+
+Detect if libatomic should be linked in or compiler and platform can
+provide the needed atomic instrinsics, this helps build on certain
+platforms like mips or clang/i386
+
+Fixes
