This is needed for the COMPATIBLE_MACHINE feature as well as writing one 
recipe that can be reused for different machines/distros with slightly 
different configurations.

Here are some examples:
  - Creating a custom debian based distribution by patching debian 
certain packages, but still being compatible to the debian distribution 
and reusing their `:debian-bookworm`, etc overrides, where applicable.
  - Creating BSP package layers that support multiple different boards 
with the same or a different soc, where some packages/recipes are soc 
specific, some are board specific.

All of that is possible with other means, but using the *OVERRIDES and 
COMPATIBLE_* variables is the most straight forward and accustomed way 
for developers coming from OE.

In my case, I am integrating a couple of boards based on different tegra 
variants in one BSP.

Claudius
