First, "make NO_KERNELCLEAN=yes buildkernel" avoids cleanup of build directory
and allows reuse of previously built object files corresponding
to unchanged sources - use for relatively minor changes, not after switch
to another major release sources.

Then, "make NO_KERNELDEPEND=yes buildkernel" skips lengthy rebuild of dependencies -
use if you has not changed kernel configuration since previous build.

And "make MODULES_WITH_WORLD=yes buildkernel" skips rebuild for whole bunch
of kernel modules while building just kernel.

You may combine these: make NO_KERNELCLEAN=yes NO_KERNELDEPEND=yes MODULES_WITH_WORLD=yes buildkernel.
This way decreases build times dramatically.
