It didn't give a fail message, it opened a graphical box asking me to authenticate the creation of the loop device. It requested this and I entered the password and it mounted the loop device.
I suspect the authentication would just be ignored in the normal build environment and the authentication box would not be shown.
I then umounted loop device from /mnt/ and then reran the mount command with strace. This time I didn't get asked for authentication. My sudo keeps any authentication for some time before requiring it again.
This is what the strace provided.
ipfire build chroot (x86_64) root:~$ strace mount -o loop /tmp/test.img /mnt/
