Marek,

This now builds but the LTO steps do take noticeably several seconds
longer than without LTO (13 seconds without CONFIG_LTO vs 23 seconds
with) which is a bummer for development workflow.
You can of course play with building this as well... if you need me to
boot test something I can do that for you (and this does boot just
fine).
Best regards,
Tim
