This seems to be quite a strange issue indeed:  Out of curiosity I tried
the same thing in a VM (guix system vm-image) and even though it is the
same architecture (x86_64) and the same commit 
(e2721a05e7d778bdf845b7cb7a42fd9f76095b69) guix consistently succeeds to
build maxima in the VM while it consistently fails to build on my
laptop.  I also tried building with only one core on my laptop and
running the VM with two cores (qemu-system-x86_64 -smp cores=2) with the
same result.  `guix build maxima' only fails on the VM when I run it
with `--rounds=2' because the outputs differ.
