[bitbake-devel] [PATCH] cookerdata: Issue warning if layer doesn't set LAYERSERIES_COMPAT_x

[Richard Purdie]

We'd like layers to set this variable so that we know which layers are compatible
with which others, even if the branch is a generic un-updated "master" branch.

Start printing a warning to highlight this issue.
