bug#46537: ‘uname -s’ from Gash-Utils-Boot returns nothing

[Ludovic Courtès]

Gash-Utils ‘uname’ seems to be confused:

--8<---------------cut here---------------start------------->8---
$ $(guix build -e '(@@ (gnu packages commencement) gash-utils-boot)')/bin/uname 
-a
Linux ribbon 5.10.10-gnu #1 SMP 1 x86_64 GNU/Linux
$ $(guix build -e '(@@ (gnu packages commencement) gash-utils-boot)')/bin/uname 
-s
