Description of problem:
RH 9 deleted these lines from kernel.spec

# allow --with[out] <feature|kernel> at rpm command line build
# e.g. --with smp --without smp --without BOOT --without bigmem --with  ibcs
# --with overrides --without
%{?_without_up: %{expand: %%define buildup 0}}
%{?_without_smp: %{expand: %%define buildsmp 0}}
%{?_without_BOOT: %{expand: %%define buildBOOT 0}}
...

so rpmbuild ignores --with/--without on the command line when building 
the kernel.

The lines were in RH 8 (kernel-2.4.18-14.src.rpm), they are also
missing from the latest RH 7, 8 and 9 errata kernel.spec files
(kernel-2.4.20-18.[789].src.rpm).

There is nothing in the changelog about removing this facility and the
kernel.spec comments still say that --with/--without can be used.

On the same subject, what do these lines do?  Nothing seems to test
the defined macros.

# we can't test values inline, only whether a macro exists
%{expand: %%define buildup_%{buildup} yadda}
%{expand: %%define buildsmp_%{buildsmp} yadda}

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. rpmbuild -ba --without smp kernel-2.4.spec
2. 
3.
    

Actual Results:  --without smp ignored on rh 9 and recent rh [78] errata 
kernels.

Expected Results:  Build without any of the SMP kernels.
