oh, then maybe it's not necessary. I honestly don't even know where
the authoritative source code of libelf is, so I just found some
random source code with Google.

The elfutils.org libelf implementation can be found here:
https://sourceware.org/git/?p=elfutils.git;a=tree;f=libelf;hb=HEAD

There are some other implementations, but some aren't maintained and
others aren't packaged for any distro (anymore). libelf is a semi-
standard "SVR4 Unix" library, so you might also find it for some none
GNU/Linux OSes like Solaris. The ELF specification itself is contained
in the System V Application Binary Interface (gABI). The libelf library
itself isn't actually officially part of the specification. But we
still do try to keep the implementations (source) compatible through
the generic-abi mailinglist.

Cheers,
