BR2_GCC_ENABLE_LTO only enables LTO in the toolchain, not in packages. Use BR2_ENABLE_LTO instead to enable it in packages as well. Note that BR2_GCC_ENABLE_LTO is currently non-functional (LTO is still enabled in the toolchain even if it's not set), so we *do* have LTO available in the toolchain. Note that the option has no effect at all on these defconfigs anyway, since they don't contain any package that is affected by the BR2_ENABLE_LTO option. Still, it makes sense to enable it for these really memory-constrained targets for when packages are added.
