Hi Helmut, Thanks for offering to help with cross building. Let me first comment on the following.

The above statements are not true. While rewriting d/rules to build GHC using Hadrian, I tried very hard to implement cross-building for GHC. I backported upstream fixes [1], engaged in upstream discussion about this [2] and we concluded that the new Hadrian build system is not capable of cross-building GHC [3]. Upstream is working on fixing this, but it's a slow process [4]. This is why we have the error message there, and if you look at the d/rules file, you will see it has comments that link to these upstream issues. With that said, I am happy to share everything I have seen while trying to make cross-builds work, and we can work together to support this.
