This is cool. I though I'd try to do it myself, but you was faster ;-)

That's actually the only thing I needed.

Well, actually, I'm already use Boost.Build, so I do dynamic linking to all 
targets without -load, and don't have to rebuild llc already ;-) The change 
is still good, because it eliminates the need to declare all targets in one 
place and besides, using -load is good sometimes.
