This is the fuzzer from #21454 (comment). I finally got it to compile. The fuzzer isn't supposed to be merged because it's kind of kludgy due to that part of the code not being test-friendly in general. But it should be enough to start fuzzing parse_elf. Happy fuzzing! To get it to work either elfutils has to be compiled with libFuzzer and passed via LD_LIBRARY_PATH='path-to-libelf;path-to-libdw' or a corpus of some kind should be prepared to keep it going.

Generally I turn off this part of systemd (along with systemd-coredump) so I'm not particularly interested in fuzzing it any more. I think it can be closed.
