But is the problem that we just fails to detect the *build* platform, and thus generates build tools for x64, instead of aarch64, which makes the build fail? (Also, why doesn't the rosetta-equivalent kick in in that case?)

Or do we also fail to set the proper target platform, so that building on windows/aarch64 will in effect be a cross compilation to x64?
