Currently, Kotlin/Native support cross-compilation only to a restricted set of https://kotlinlang.org/docs/reference/native-overview.html#target-platforms. Since 1.4.30 it is also possible to tune these targets via "-Xoverride-konan-properties" flag. But this approach is clearly limited. Without patching and recompiling the K/N distribution it is impossible to compile for a target that is not predefined. So it would be great to lift this restriction and allow users to define their own targets (for example, like it is done in https://mesonbuild.com/Cross-compilation.html). The problem is it will not be sufficient to support arbitrary cross-compilation only in Kotlin/Native backend (which is a big task by itself). A proper solution requires changes in different parts of Kotlin, including but not limited to: Gradle plugin, cinterop and klib infrastructure. If you vote, don't hesitate to add your use-cases in comments. It will help us to design the best solution :) Related GitHub discussions: * https://github.co…
