Normally this kind of thing is only doable for sources that are already independent of the top-level configury -- drop-in stuff like gmp or libiconv, or roots of the tree like libiberty and gnulib.

I tried with just bfd, it doesn't work (with the default Simon> configure options at least) because it requires zlib being built. Yeah, most of the things that are "really" in-tree have dependencies and can't be built independently of the rest. Tom
