I see that ci.guix.gnu.org's builders seem to run out of memory while
building kernel headers for i686-linux:

------
xz: (stdin): Cannot allocate memory

This looks like more of the too-many-cores while decompressing tarballs
issues we've had in the past on i686-linux. Can we change that phase to
use a maximum of 4 cores or would that cause everything to rebuild?
