Editing the config files manually doesn't always work.

What I would try is this: (Note that I haven't actually done this, these 
commands are off the top of my head and may need adjusting)

First, if your building rpms as 'root' set up a non-root rpm environment.
I have directions and a script here:
http://www.tuxfan.homeip.net:8080/hack.html

(Everything below assumes a non-root environment setup in ~/rpmbuild)
Once set up, I'd install the kernel*.src.rpm package.
$ rpm -ivh kernel*.src.rpm

$ cd ~/rpmbuild/SOURCES/kernel-2.4.20
$ rpmbuild -bp kernel-2.4.spec
(Builds through the %prep stage, installing and patching the source.)

$ cd ../../BUILD/kernel-2.4.20/linux-2.4.20/
$ mv configs/kernel-2.4.20-i586.config \
   configs/kernel-2.4.20-i586.config.orig
$ cp configs/kernel-2.4.20-i586.config.orig .config
$ make config (making your changes)
$ diff -Nau configs/kernel-2.4.20-i586.config.orig \
    configs/kernel-2.4.20-i586.config > \
   ../../../SOURCES/kernel-2.4.20/myi586patch.patch

(and again for the changes to the i386 kernel)

Add the needed 2 lines in the spec file to include each new patch:
Patch12000: myi586patch.patch
%patch12001 -p0
Patch12000: myi386patch.patch
%patch12001 -p0

Perhaps try rpmbuild -bp again, make sure the patch applies properly. If 
so, then try building the package again.

I use a similar command line, but I edited the specfile as well. Here's my 
patch:
$ diff -Nau kernel-2.4.spec.orig kernel-2.4.spec

Then, I built with:
rpmbuild -bb --target i386 -without BOOT --without smp --sign 
kernel-2.4.spec

> Why there is no kernel-2.4.20-8.i386.rpm ?

I ended up with:
$ ls ../../RPMS/kernel-*
../../RPMS/kernel-2.4.20-8RULE.i386.rpm
../../RPMS/kernel-doc-2.4.20-8RULE.i386.rpm
../../RPMS/kernel-source-2.4.20-8RULE.i386.rpm

Hope that's both understandable and helpful. ;)
