As said in my small HOWTO:

% It is necessary, at least from my own understanding, to "make
% prep-kernels" in order to create the kernel build directory.  Indeed
% if you put your .config file directory into the kernel tree, the
% kernel's build system will complain about its cleanliness and will ask
% you to run "make mrproper".  The reason is that the kernel is not
% built directly in the source tree -- as most of people used to do --
% but instead uses a separate directory to store produced object files,
% thus the assumption about the cleanliness.

I admit this could be stated in better english, though :).

To make it short: "make prep-kernels" create a build directory for the
kernel ***where you can copy your .config file***.  DO NOT CREATE A
.config FILE IN THE KERNEL SOURCE TREE.

Concretly:
% xentest:~/build/xen-3.2.0# make prep-kernels
% [...]
% make[3]: Leaving directory 
`/root/build/xen-3.2.0/build-linux-2.6.18-xen_x86_32'
% make[2]: Leaving directory `/root/build/xen-3.2.0'
% make[1]: Leaving directory `/root/build/xen-3.2.0'
%
% xentest:~/build/xen-3.2.0# cp /path/to/your/.config 
build-linux-2.6.18-xen_x86_32/.config
%
% xentest:~/build/xen-3.2.0# make dist
% [...]

I hope this will be clearer now.
