I haven't tried using the results of a 'make buildkernel' to do this,
it might not work. There is all sorts of magic stuff going on that
places the results of 'make buildworld/buildkernel' in /usr/obj.
Assuming a 5.X based i386 system I would do this:
cd /usr/src/sys/i386/conf
config GENERIC
cd ../compile/GENERIC
make depend
make tags
vi -t connect
The same basic thing works on 4.X systems but the pathnames are a tiny
bit different (mostly just "cd ../../compile/GENERIC" instead).
