I'm still not sure how this gets around the uname -a stuff I  
simplified the changes I'm asking for and I don't see why walking the  
argument list twice looking for --target= is an issue.  Seems fairly  
clean to me.

I suggest we move the uname -a stuff to the same place we handle the  
arch= so thats put together.  Then allow for targetos to be  
overwritten before any actions are taken on the host os.  If  
something like this is not handled then cross compilation where the  
host os differs is just not possible.
