As per the Yocto Project guidelines, layers that do this are broken.  A BSP
layer should only introduce changes that affect the BSP, distro layers
shouldn't contain general purpose recipes, and everything that is
distro-specific should be isolated using overrides.

If a layer breaks these rules in dramatic ways I'd start by filing a bug or
patches, but you may find the whitelist class useful:
