This is a good point.  We need zlib in the gcc repository because we
build it for the target, but this issue does not arise in the src
repository.  So this becomes a question for the binutils maintainers: do
the binutils want to be self-contained, or do they want to follow the
path of gcc and require additional libraries to be installed before a
build can succeed?
