Yank libc 0.1.0 to 0.1.4

[LunaBorowska]

libc versions 0.1.0, 0.1.1, 0.1.2, 0.1.3 and 0.1.4 don't compile anymore. This makes it more annoying to use cargo update -Z minimal-versions. Could those versions be yanked? This won't affect ancient versions of Rust, as I doubt those versions are capable of using crates.io-index nowadays.

I'm fairly sure that these old versions aren't used now but also doubt if it's worthwhile to yank them just for one nightly feature.

I agree its not worthwhile. IMO, Better to fix minimum allowed libc in all (transitive or direct) dependencies where it violates those MSRVs. This failure to set appropriate minimums is of course exacerbated by the fact that libc has failed to release a 1.0, see #547 (comment).

Closing in favor of the above reasons, thanks for reporting.
