uutils-coreutils sets PROVIDES/RPROVIDES = "coreutils" and is a drop-in replacement that cannot coexist with GNU coreutils; both ship the same update-alternatives links. meta-oe/conf/layer.conf already selects between them with PREFERRED_PROVIDER_coreutils{,-native,nativesdk-}, defaulting to GNU coreutils. PREFERRED_PROVIDER only disambiguates providers reached through a dependency, not recipes built as explicit targets. Since uutils-coreutils was in world, 'bitbake world' and 'bitbake universe' pulled both recipes into the same task graph as targets, so bitbake reported: NOTE: Multiple .bb files are due to be built which each provide coreutils: NOTE: Multiple .bb files are due to be built which each provide coreutils-native: NOTE: Multiple .bb files are due to be built which each provide nativesdk-coreutils: Key EXCLUDE_FROM_WORLD off the selected provider so only the chosen implementation is built in world/universe. Building uutils-coreutils explicitly, or selecting it via PREFERRED_PROVIDER_coreutils, still works. This follows the existing conditional EXCLUDE_FROM_WORLD idiom used by mpv, sox and vlc.
