I actually think pkgconfig(systemd) is a mistake in the spec file..

This brings in the libraries:

  BuildRequires:  pkgconfig(libsystemd)

This is does something else and isn't needed, AFAIK:

  BuildRequires:  pkgconfig(systemd)

Same with udev:
  BuildRequires:  pkgconfig(libudev)
vs
  BuildRequires:  pkgconfig(udev)

But you explained in the past suse needed actual udev installed for some
reason I can't remember..

I suspect Tatyana has an old version of suse where
'pkgconfig(libsystemd)' doesn't do the right thing.

I suspect the issue is that old versions of suse probably have the old
arrangement of systemd libraries that were split into three libraries
(libsystemd-journal, libsystemd-id128, and libsystemd-daemon)
so pkgconfig(libsystemd) isn't going to work (and rpmbuild should fail
fail, why doesn't it??)

Probably something like

BuildRequires:  pkgconfig(libsystemd) | (pkgconfig(libsystemd-journal), pkgconfig(libsystemd-id128), pkgconfig(libsystemd-daemon))

If RPM can do that, otherwise a suse version conditional?
