I'm astonished it only complained about unresolved symbols. If you
leave it as is, it tries to link in your build system's libraries. I
always replace the two with full paths to the mips libraries. I'm
fairly sure this is also in my cross-build faq.

>From make-cross.sh:

        # *sigh* This is the fun part. We need to fix up libc.so so that
        # it points to files in our filesystem, not the mythical /usr dirs
        # we would have if this were native.
        echo "Fixing up libc.so locations"
        sed -e s%/lib/libc.so.6%"${_destdir}/$TARGET/lib/libc.so.6"%g \
            -e s%/usr/lib/%"${_destdir}/$TARGET/lib/"%g \
          < "${_destdir}/$TARGET/lib/libc.so" \
          > "${_destdir}/$TARGET/lib/.new.libc.so" || exit 1
        mv -f "${_destdir}/$TARGET/lib/.new.libc.so" \
          "${_destdir}/$TARGET/lib/libc.so" || exit 1

Finding a nicer way is left as an exercise...
