Rework ordering and definition of targets.

Move ordering of targets to the very end of bsd.port.post.mk and make it define dynamically
Now all targets should be defined prior to the end of bsd.port.post.mk to allow .ORDER to control
the sequence of the targets properly.
From now all structural targets should also be defined in one of the _SEQ variable.
Extra bonus only the really defined targets are set in the final order sequence meaning that we do
not need anymore to create a ${DO_NADA} fallback target anymore, which improves performance and
simplify debugging.
