  Yes, exactly.

  Almost right, but two things:

1)  If you specify --host and --target, you'll need to specify --build as
well, otherwise configure will assume it's the same as the other two and that
you're trying to do a native build.

2)  Don't *ever* refer directly to the configure scripts below top-level.  You
/must/ always invoke top level configure.  Let it do the recursive stuff.  You
don't need to build the whole tree even though you need to run the top-level
configure, you can always specify "make all-target-bfd" on your command line.
