this macro should be defined as `150300` however it is not present in
`/usr/lib/rpm/suse/macros` provided by
`rpm-config-SUSE-1-3.61`:`suse_macros.in` for Leap 15.3

```

%supplements_kernel_module() \
    %{expand:%(if ! rpm -q kernel-syms > /dev/null; then echo "%fail Please add
the kernel-syms package to BuildRequires"; fi)}

%suse_version @suse_version@
%sles_version @sles_version@
%ul_version @ul_version@
%is_opensuse @is_opensuse@

%do_profiling

contrast to `/usr/lib/rpm/suse_macros` provided by
`rpm-4.14.1-lp152.17.5`:`rpm-suse_macros`

```

%supplements_kernel_module() \
    %{expand:%(if ! rpm -q kernel-syms > /dev/null; then echo "%fail Please add
