This changes the build process as outlined in my email earlier this week.

Essentially we now build the static objects, then allow a platform to run
a given command, build the shared modules, then run another command before exiting.

This gets us building dso's on beos and may provide a better framework for some of
the other "strange" platforms out there without stopping the normal ones working.
