I doubt that.

I've looked at this and think it's possible. The code at the end of gcc.jam -- 
which sets threading options --- would be become function like 
'init-linker-flags'. However, that's a bit of work, and it's not clear if 
that work is needed.

I've decided to apply the patch as-is. Thanks!
