[BusyBox] uClibc build problems (was: autoconf stuff)

[Tom Cameron]

 Is this an easy fix?  Am I understanding you correctly in that _res needs
to be added into resolv.h, or does an include need to be added?  Just
wondering.  Otherwise, things work GREAT.

Yep, as Erik indicated _res is not in the resolv.h that is part of
uClibc
so that is the problem with compiling nslookup.c.
