What architectures are targeted?

Hello,

I am wondering what architectures are targeted.

I ask this because I can't build guile-goblins on aarch64 using guix, then I tried using guix repl, bootstrap, configure and make but there are several fails during make check, also "caught error". I even got a segfault during a make check.

If aarch64 is a legit target, I would like to help.

Thank you!
