You could try to comment out the socket.c line about setsockopt 
IPV6_RECVPKTINFO and see if the error goes away (likely radvd doesn't 
work, but that could give an indication if this is the reason).

I'm guessing this is a problem in that version of uClibc.  You could 
try to look at the changelogs or code for clues, or try 0.9.30.
