Library build

[davidmartos96]

Hello! I'm starting out with Zig. My idea is to use it to build a cross platform library to use through FFI Dart in Flutter, so that it can be used from Android and iOS.

I was wondering if it is possible to adapt the example to turn a Zig library into a ".a" file for iOS that it can then be linked statically through the XCode configuration, instead of building the iOS app binary itself with Zig.

That kind of example could also help people using React Native for mobile development.

Thanks!
