new iOS build error with rust 1.45

[extrawurst]

building the hello world example for iOS (cargo lipo) spits out tons of these since rust 1.45:

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

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

I am on macOS and fresh rust 1.45.

any idea what this is about? do I rather need to go to cargo-lipo for this?

I'm not sure if this is related to something in godot-rust itself. I personally have never heard of the +cyclone flag. It seems like that the build error is emitted for multiple dependencies as well, scopeguard, nom, and regex for example. This seems to suggest that the issue might be in cargo-lipo or somewhere else on the toolchain, rather than individual crates.

Seems to be a regression in rust itself: rust-lang/rust#74427

this seems fixed now. just checked with rust 1.46
