That worked perfectly. Thanks very much, Peter!

You are presumably using a merged /usr (BR2_ROOTFS_MERGED_USR), where
/lib should be a symlink to /usr/lib, so when you add a rootfs overlay
containing a /lib directory this is no longer valid and it complains.
Simply put your files in the overlay under /usr/lib/.. instead.

You may consider moving to 2019.02.9 for a number of (security) fixes
since the 2019.02.6 release, and also notice that the 2019.02.x will go
end of life in approximately 1 month, so consider updating to 2020.02
(once released at the end of the month).
