But open succedd - because we see no output from that one.

They are generated by kbuild. See scripts/Kbuild.include:
# Execute the command and also postprocess generated .d dependencies file. if_changed_dep = $(if $(strip $(any-prereq) $(arg-check) ), \ @set -e; \ $(echo-cmd) $(cmd_$(1)); \ scripts/basic/fixdep $(depfile) $@ '$(make-cmd)' > $(dot-target).tmp;\ ==> rm -f $(depfile); \ mv -f $(dot-target).tmp $(dot-target).cmd)
If you delete the line marked "==>" then you should have .d files are a build.

These looks unrelated.
