This is doable at least when dealing with ELF objects. Of course the binary
has to _both_ provide a program entry point (likely as a weak symbol, so it
can be overriden when the ELF object is linked in as a shared library), and
also export dynamic symbols. You can try this today, by going ahead and
executing the glibc main binary:

  % /lib/libc-2.25.so
  ...

Of course, building such a binary can get tricky (symbol visibility, weak
symbols) and most likely it will be a portability nightmare. Still doable,
though!

Cheers,
