configs/*: use BR2_ENABLE_LTO to enable LTO instead of BR2_GCC_ENABLE_LTO

Browse Source 
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.
