patch 155 (linux-2.2.16-rhconfig.patch) breaks the way the arch is
determined. I modifies the make *config for the kernel so that instead of
looking at the build arch to determine which config file to use for the
kernel build, it looks at your current system type. This means that if I'm
on a 686 box and do a 'rpm --target=i586 --rebuild
kernel-2.2.16-22.src.rpm' it will build an rpm that is labelled as being
i585, however the actual kernel compile will make a 686 kernel, resulting
in a mislabeled rpm.
Commenting out the line where this patch is applied in the spec file seems
to solve the problem.
