Those binaries would be “cut” from the dependency graph: we’d cross-compile them from x86_64 and upload them to ftp.gnu.org. Then someone using Guix on those architectures would simply download these pre-built binaries. It’s clearly not ideal: it would be great if we had instead a bootstrap path for those compilers on those architectures. But, in the absence of such a path, using those binaries cross-built from source is better than using opaque pre-built binaries provided by upstream. Thanks, Ludo’.
