Normal linkers automatically follow any NEEDED entries, that's why they
are there after all. I'm not ruling out bugs in the linker though.
That's why on most systems you can say -lreadline and not worry about
whether it uses curses or termcap.

And in any case, if it's only libsocket it that needs and we don't use
any symbols in it ourselves, then we surely don't need to reference it.
That's purely a dynamic linker issue.

Have a nice day,
