sys/conf/NOTES + sys/<machine>/conf/NOTES

You can still use the old way of building kernels when you aren't
updating the world.  You can also use the reinstall target in
conjunction with -DNO_MODULES to just reinstall the kernel.

If you just want to change some options and you still want to use the
new way, the unsupported workaround is:

make -DNOCLEAN buildkernel

It still configured the kernel and does a "make depend", but it won't
delete the object files which speeds things up a lot.  It does fail from
time to time though so be sure to try without -DNOCLEAN before reporting
breakage.
