.... but nothing is bug free, there are documented cases of LTO
causing issues. So until we get a distro knob to turn this off an on,
what about something like ?
CFLAGS_LTO ?= "-flto"
LDFLAGS_LTO ?= "-flto"
CFLAGS += "${CFLAGS_LTO}"
LDFLAGS += "${LDFLAGS_LTO}"
So if we run into issues, we can easily bappend the LTO flags to nothing.
