Re: Bug#939898: glibc: setuid/getuid broken on alpha with 2.29-1

Both on my Alpha XP-1000 as well as inside a qemu-user chroot, upgrading glibc
to version 2.29-1 resulted in setuid/getuid breaking in a weird way:

To reproduce, one can simply run debootstrap with qemu-user-static installed and
enter the chroot:

root@epyc:/local_scratch> debootstrap --no-check-gpg --arch=alpha --foreign --variant=minbase unstable sid-alpha-sbuild http://ftp.ports.debian.org/debian-ports
root@epyc:/local_scratch> chroot sid-alpha-sbuild
bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)
I have no name!@epyc:/local_scratch> ./debootstrap/debootstrap --second-stage
E: debootstrap can only run as root
I have no name!@epyc:/local_scratch>

I assume this would also work on qemu-system-alpha although I haven't tried
yet. But it should work the same way but without the "--foreign" argument.
