Subject: [oe][meta-oe][PATCH] syslog-ng: workaround segfault for ppc64le

For now syslog-ng segfaults on ppc64le. The problem could be reproduced by simply adding syslog-ng to IMAGE_INSTALL and then building and starting an image for qemuppc64.

The underlying root cause is hard to find. This workaround helps improve the situation a little bit so that users can at least use syslog-ng on ppc64le targets.

Note that this workaround should be dropped once the upstream issue gets a real fix: https://github.com/syslog-ng/syslog-ng/issues/4285
