[linux-yocto] [PATCH 02/10] meta: Add lto-disable feature

[Alejandro Hernandez]

From: Tom Zanussi <tom.zanussi at linux.intel.com>

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"
