When CONFIG_MODULES is disabled, 'make (bin)rpm-pkg' fails:

  $ make allnoconfig binrpm-pkg
    [ snip ]
  error: File not found: .../linux/rpmbuild/BUILDROOT/kernel-6.10.0_rc3-1.i386/lib/modules/6.10.0-rc3/kernel
  error: File not found: .../linux/rpmbuild/BUILDROOT/kernel-6.10.0_rc3-1.i386/lib/modules/6.10.0-rc3/modules.order

To make it work irrespective of CONFIG_MODULES, this commit specifies
the directory path, /lib/modules/%{KERNELRELEASE}, instead of individual
files.

However, doing so would cause new warnings:
