No, sorry, I can't really tell how to extend the bionic libc. I've never
seen such a system. You might get away without telldir and seekdir
by implementing the readdir semantics in a VFS module and intercept
telldir/seekdir. You could either do the full readdir scan at opendir time
and cache the results in a fsp extension. The slightly more complicated
variant is to do the NEXT_READDIR on demand.

With best regards,

Volker
