Kernel source is existing git repo I just "git pull" from and I did not do any "make clean" or "make-kpkg clean" on it before.

I bet there have been "*.cache.mk" files around from previous pre gcc-7.3 compiles. Trying again after % find -name ".cache.mk" -delete on kernel source tree. Will report back. Thanks, -- Martin
