Hello MIPS Guix! A failing test in glib alerted me to a bug in libffi on MIPS N32. I've pushed a fix[*] to the 'loongson' branch. It will require rebuilding quite a few packages, so I recommend aborting whatever builds you have running, and pulling the latest 'loongson' before continuing.
Best, Mark [*] http://git.savannah.gnu.org/cgit/guix.git/commit/?h=loongson&id=376069c09e796b6aef9eb3a524c991c4a41ff594
