The only valid target for i686 is config-i686-PAE.
Look in the ~/rpmbuild/SPECS/kernel.spec file (search
for Source32), or ls ~/rpmbuild/SOURCE/config* before 
you copy anything to it to see the list of valid values.

Because the two config names you are using aren't valid in the spec
file, they are being ignored and the generic Fedora kernel is being
built.

See the link 
http://fedoraproject.org/wiki/Building_a_custom_kernel
for a better command.

rpmbuild -bb --with baseonly --with firmware --without debuginfo --target=`uname -m` kernel.spec

This should build headers for you.
