Are there any toolchain support changes or is SLE 15 SP4 userspace suitable?
Are there kernel.org branches should LTO enabled vs disabled?

Factory as userspace would be problematic as it keeps changing and has limited
to no remote deployment support currently available. I also need to have an
idea of what patches are applied just to make LTO an option because the real
comparison should not be between LTO enabled vs disabled but between vanilla
mainline vs LTO-disabled vs LTO-enabled. Given that it is expected to be
fragile and likely break, it'll be only queued against one machine as a
starting point.
