Error building for `apple-ios-macabi` target

[jurvis]

Hello, I'm trying to build this library for Mac Catalyst targets, specifically aarch64-apple-ios-macabi and x86_64-apple-ios-macabi.

However, when running cargo build, I get the following error:

❯ cargo build --target x86_64-apple-ios-macabi --release --lib                                                                  ⏎
   Compiling secp256k1-sys v0.5.2 (/Users/jurvistest/Projects/rust-secp256k1/secp256k1-sys)
The following warnings were emitted during compilation:

warning: clang: error: invalid version number in '--target=x86_64-apple-ios13.0-macabi'

error: failed to run custom build command for `secp256k1-sys v0.5.2 (/Users/jurvistest/Projects/rust-secp256k1/secp256k1-sys)

Here's the full build output: https://termbin.com/dulp

any ideas?

sorry, learned that this is likely due to an upstream issue with cc to be addressed in rust-lang/cc-rs#678

Thanks for digging into it!
