Add option to enable GCC LTO
Add CONFIG_LTO to use GCC Link-Time Optimizations to try to reduce the
flash footprint of the firmware.
Add additional protection to some functions/data to avoid removal by the
linker when their usage is not obvious.

BRANCH=none
BUG=none
TEST=make buildall (with and without LTO enable on all boards)
