You say you are building libunistring, but from the file names it looks
like you have built libunistring successfully and are now building wget?

In other words, please give the steps to reproduce.

Also, have you followed these instructions from the HACKING file?
  Each time you want to update the source, do not only "git pull".  Instead do
    git pull && ./gitsub.sh pull
    ./autogen.sh
