What you say here doesn't make a lot of sense... The kernel is typically not an
ELF file (well, the vmlinux image is but that's not what you normally use), and
on the target system you typically don't have a readelf executable... So what
exactly are you doing here?

That could explain the "wrong magic bytes" thing. Maybe you're trying to use
your little-endian host readelf to check the target executable? That's not going
to work, you need the cross-readelf (output/host/bin/*-readelf).
