It appears this has been broken for quite some time, likely before LEDE forked from OpenWrt, as there are CC builds with initrams images working fine (early 2016), however the CC repo no longer compiles a working initrams image, nor does LEDE.
-
The changes causing the issue appear to have occurred between 2016.02.18 and 2016.09.06
- I have a working OpenWrt initramfs image created 2016.02.17 @14:26:46 UTC which boots w/o issue.
-
This post from the SolidRun forum on 2016.09.06 @ 10:30am (local) verifies boot issues occurring at least as of this date.
-
(Xue Liu's [clockworkbird9] repo is mentioned and a link to his blog is provided, however he either forked OpenWrt prior to the issue originating or fixed whatever was broken.)

A LEDE initramfs image is a mess all around:

Include kernel in root filesysteminclude uImageinclude zImageinclude FIT
-
Include DTB in root filesystem

Booting a LEDE zImage goes a bit better... until the kernel panic:
