The buildkernel target will run a "make clean" before building the new kernel, in an effort to be on the safe side. This will delete all the old kernel's object files (anything that had been compiled before the interruption took place). Thus, all files will be compiled again... This is exactly what the original question was about. -DNOCLEAN inhibits the Makefiles from running "make clean". I don't know if this is a sufficiently explanatory answer, but anyone curious enough can always look up the exact commands that the buildkernel make target runs at /usr/src/Makefile.inc1 :-) Giorgos.
