make buildkernel fails without complete source tree

[Marc René Arns]

Dear documentation team

as opposed to the process meantioned here:

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-building.html

it is not sufficious to have the kernel sources to build a kernel with

# cd /usr/src
# make buildkernel KERNCONF=GENERIC

This results in the message

# make: don't know how to make buildkernel. Stop

The reason is that the Makefile in /usr/src is missing when getting the kernel 
sources via sysinstall.

Tested with 6.2 release.

Even if it is a bug I think that as long as it is this way it should be 
reflected in the handbook.

Thank you for your great work!

Regards,
Benny
