Wouldn't it be better to remove the "recurse to get the Env etc." magic? 
  My understanding is that ultimately we want to get rid of having to 
source Env.Host.sh by replacing it with a file included by gbuild.mk, 
not by sourcing it behind the scenes, right?  Once we are there, 
toplevel make command line arguments should behave as expected.  I see 
no need to break that in the meantime.
