 I think target-finalize should depend on all other target-*. It's
something that you may want to call from the command line in order to get
an up-to-date target directory.

 toolchain-eclipse-register can be done in parallel with all the rest, it
should just depend on toolchain. There is nothing really that depends on
it, so probably 'world' is the best choice.
