For the record, I’ve successfully run the following command on my A20
OLinuXino with a bit less than 1 GiB of RAM:

  guix pull --commit=380c3e459b6ebf0077008886954ff881a0cc7924

It takes ages, but fortunately substitutes were available for this
revision.

Before substitutes were available, it went OOM (out of memory) as in
your case while building guix-system.drv.

‘guix pull’ is still barely usable on these low-end devices, though with
Guile 3.0.3 it’s better.
