On arm64, ppc64el and s390x there's this error:

Test suite properties: RUNNING...
properties: unknown RTS option: -N

Is this because the runtime doesn't do threads on those architectures?

I found this in the debian/changelog dated Sep 2012:

  * Enable test suite on architectures with threaded runtime.

Is the build script supposed to detect whether the architecture has a
threaded runtime?

This Debian bug mentions a test for a threaded runtime that didn't
work:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=737637

By the way, does anyone know if any of those architectures has a
threaded runtime in the latest upstream versions of GHC, and what is
involved in implementing the threaded runtime?
