Not sure how much of a difference it makes, but I run this command
instead:

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix build coreutils --target=i586-pc-gnu -K

… but as you can see the end result is the same.  :-)

I think we can skip this issue though: since ‘core-updates’ has
glibc 2.28, how about merging ‘glibc/linux’ and ‘glibc/hurd’ on
‘core-updates’, removing the Hurd’s ‘libpthread’, and starting from
there?

(Note that the two glibc packages must be merged in a way that does not
involve a full rebuild because ‘core-updates’ is frozen now.)

Thanks,
Ludo’.
