Sorry for the delay again. Since it touches the cross toolchain and not
the main toolchain (Manolis, could you double-check that this is
correct, by making sure that “./pre-inst-env guix build coreutils -d” is
the same both before and after the patch?), it’s still OK to push to
‘core-updates’.
Manolis: OK to push?
Thanks for the heads-up, Efraim!
