[Luo Zhenhua-B19537] Seems like the similar issue as https://bugzilla.yoctoproject.org/show_bug.cgi?id=4309

[Luo Zhenhua-B19537] Generally "were installed but not shipped" means those files are installed into ${D}, but not placed in any resulting package. FILES can solve it. If the folder is empty, you can remove it directly.

[Luo Zhenhua-B19537] I am not sure whether such variables are documented in a unified doc, I always check it in meta/conf/bitbake.conf or "bitbake -e | grep xxx".
