At some point, I predect we're going to end up needing a MANIFEST file,
we might as well do it now. Then that covers us from all possible
directions. Right now things work for ELF, but someday somebody will want
COFF, or CE binary format or something like that and it will through the
universe into flux. If we have the manifest file, then we are covered
in all cases.
