I'm hardly an expert in such things but it looks to me as if gcc is ordering things differently between the two builds: https://tests.reproducible-builds.org/debian/dbd/unstable/arm64/systemd_247.2-4.diffoscope.html#systemd-tests_---.---_arm--.deb---data.tar.xz---data.tar---.-usr-lib-systemd-tests-manual-test-udev---objdump---line-numbers---disassemble---demangle---reloc---no-show-raw-insn---section-.text--- and all the other differences follow on from that. Unless systemd is using particularly strange compiler options, it's unlikely to be a systemd packaging issue.
