Is this happening at the final link stage?  If you configured with
--enable-shared, then Octave should not be expecting to find these
symbols in liboctinterp.  Instead, they should only be in the
corresponding .oct files, which are loaded dynamically.

I suspect Octave is somehow misconfigured.  Did you have some files
left over from a previous build?  If so, I'd suggest starting with a
fresh copy of the sources.
