GNU linkers gracefully exit in that case. This patch makes lld behave like GNU. Note that even with this patch, lld's -v and --version options behave slightly differently than GNU linkers' counterparts. For example, if you run ld.bfd -v -v, the version string is printed out twice. But that is an edge case that I don't think we need to take care of.
