The BR2_GCC_ENABLE_LTO config used to enable LTO on compiler level. That config symbol doesn't exist anymore. Instead, LTO is enabled by default with GCC. However, there is a new flag named BR2_ENABLE_LTO which enables LTO in packages. So far it doesn't look like that packages we are using support the flag, but that might get added in the feature. Opt-in already today.
