With a directory-structure like
/
├── repo
│ └── layers
│ └── meta-my-layer
└── work
├── build
└── layers
└── external
├── meta-openembedded
│ ├── meta-networking
│ └── meta-oe
└── poky
└── meta
and
# Set through bitbake itself
COREBASE = "/work/layers/external/poky"
TOPDIR = "/work/build"
# Set in bblayers.conf
BBLAYERS = " \
/repo/layers/meta-my-layer \
/work/layers/external/meta-openembedded/meta-networking \
/work/layers/external/meta-openembedded/meta-oe \
/work/layers/external/poky/meta"
The resulting eSDK layers directory will look like this:
.
├── meta-my-layer
├── meta-openembedded
│ ├── meta-networking
│ └── meta-oe
└── poky
└── meta
Without this patch the /repo/meta-my-layer layer broke the build:

Without meta-my-layer this patch should not cause any change.

would remove the special casing in the implementation (except for COREBASE
sublayers), thus resulting in the following layer structure in the eSDKs layers
directory:
.
├── meta-my-layer
├── meta-networking
├── meta-oe
└── poky
└── meta
