Hello Ludo',
Thank you for looking in to this.
The 'testsuite.log' file you requested is attached.
I noticed that in the "Detailed failed tests" section, it has:
68. commands.at:893: testing nice ...
./commands.at:896: tcsh -f -c 'nice set var=1; echo $?var'

68. commands.at:893: 68. nice (commands.at:893): FAILED (commands.at:896)
So at first glance the failure appears to be caused by "setpriority: Permission denied"
I'm not sure why there'd be a permissions problem. I have the guix-daemon running as root, with the following arguments:
/root/.guix-profile/bin/guix-daemon --build-users-group=guixbuild --no-substitutes
I thought maybe it's the guixbuilder user that's having permissions problems, so I tried running the failing test myself as the guixbuilder01 user:
> sudo -u guixbuilder01 /gnu/store/nrrwyb21bn8cdc0k6pis3ggs2vayibin-bash-4.4.12/bin/bash
bash-4.4$ cd /var/tmp/guix/guix-build-tcsh-6.20.00.drv-0/tcsh-6.20.00
bash-4.4$ . ../environment-variables
bash-4.4$ ./tcsh -f -c 'nice set var=1; echo $?var'
0
So the test appears to work when I run it manually, but fails when it's run as part of the build process under guix-daemon.
Also, please note that /var/tmp/guix is my guix build directory, which I've set for guix-daemon via the TMPDIR environment variable. I have a zram filesystem mounted on /var/tmp/guix as ext4, but I've tried the same "guix package -i glibc-locales" without the zramfs, on my root xfs filesystem and it didn't make any difference.
