Sorry Harry, I have not looked at the 2.6 spec file. In the 2.4 spec file
there is this at the top:

# What parts do we want to build?  We must build at least one kernel.
# These are the kernels that are built IF the architecture allows and
# no contrary --with/--without arguments are given on the command line.

%define buildup 1
%define buildsmp 0
%define buildBOOT 0
%define buildbigmem 0
%define builddebug 0
%define buildjensen 0
%define buildtape 0
%define buildBOOTtape 0
%define buildUML 0

I just assumed that the 2.6 spec was the same. I know that the with/without
part was stripped out of the 2.4 but last time I checked setting the above
to 0 or 1 depending on what you need worked. Of course it has been a while
since I did this so it might have changed. :-(

I am not sure.

On archs that do not match what you are building?? IOW if you are building
i386 you only get the i386 stuff. Same for i686.

Yes, it takes a while. I usually let it run overnight.
