new error with rust 1.45

[extrawurst]

through godot-rust/gdnative#538 it came up that this might be a problem rooted in cargo-lipo

this is the output that gets generated over and over since upgrading to rust 1.45:

'+cyclone' is not a recognized feature for this target (ignoring feature)

....

scopeguard, nom, and regex for example

as the commenter points out it is generated for multiple crates when build with lipo.

this all happens with
macOS:
10.15.5 (19F101)
10.15.6 (19G73)
Xcode: 11.6 (11E708)

This problem is deeper than cargo-lipo, since I build for iOS without using cargo-lipo and still see this message. I also started seeing this after upgrading to Rust 1.45.

There's already an issue upstream: rust-lang/rust#74427
