This is a good suggestion. Currently, the main bpf compiler/instruction set related doc is living in the kernel tree

  https://www.kernel.org/doc/Documentation/networking/filter.rst

I think that is not a good place to put relocation as kernel people really don't care relocations much and
compiler/tool people may not be interested to check the kernel doc.

We need to find a different place to document some bpf compiler/tool internal stuff. I will add a little bit more
documentation in the code and in the commit message at this time. Will consider to put relocation description (maybe others)
in a public accessible document as a followup.
