Out of curiosity, what platforms use LIBFETCH right now? OsX is still on the original OpenSSL version of the source, which I think ZOL changed away from, due to licenses, do both fbsd and zol use libfetch?

I only know of FreeBSD using it.

I'm reverting that change. We're going to import libfetch for platforms that don't have it included as part of a separate PR.
