It took me an entire summer to figure this all out.

It would be that easy if everything was statically linked.

That is the correct file, and there is no special way to download it. Those steps will work. Your problems are not caused by a bad patch, but pollution from your host libc and toolchain. Dynamic linking is hard to get rid of. (I'm trying to avoid a rant here...)
If I might ask, what is your end goal? Maybe you'd have a better time starting with something like Alpine or Sabotage.
