From: Tom Zanussi <[email protected]>
Add features/lto/lto-disable, a feature to disable LTO. This isn't
really needed, since it's the default, but it makes kernel feature
selection for currently incompatible features such as tracing less
confusing - disable by adding (for example):
KERNEL_FEATURES_append_galileo += " features/lto/lto-disable.scc"
