configs: Enable LTO if available (#2713)
Browse files Browse the repository at this point in the history 
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.
