I have merged these changes but this also breaks the Yocto Project
Compatible check layer.
In reality, I think the concept of the mixin layer will always break the
Yocto Project Compatible,
because the desire of the mixin layer is to introduce a more recent version
of the one
provided by OE-core.

I'll have to revert those commits, but I'm looking for a way to do this
while maintaining
the layer Yocto Project Compatible. If anyone has any suggestions, I would
appreciate it.
