The linking we are trying to do isn't for shared libs:  We do the
pre-linking to shorten the command lines on linking things like smbd and
smbtorture, by only having one .o per subsystem.

If you support arbitrary length command lines, then we can still link
things at the final stage, per jelmer's note.  (I hope we can have a
configure option for it too, as the old style was easier for tracing
certain build issues).

I hope we can avoid that, as we are trying to prove Samba4 as
low-os-dependency.  Stratus is a good example of that.

We specifically avoid passing fds, as this isn't known to be
particularly portable.
