I'm doing that and I don't have a copy of qemu in the chroot.
But I think I forgot to pass --persistent to the script while testing.

Title:
qemu-user: $0 incorrectly always reports absolute path
Status in QEMU:
New
Bug description:
We just ran into an issue with the Perl package on Debian/m68k when
being built with qemu-user [1].
The problem can be boiled down to qemu-user always reporting absolute
paths for the shell variable $0 no matter on how the command was
invoked.
A simple reproducer is this:
On normal system (no emulation):
root@nofan:~> sh -c 'echo $0'
sh
root@nofan:~>
On qemu-user:
(sid-m68k-sbuild)root@nofan:/# sh -c 'echo $0'
/bin/sh
(sid-m68k-sbuild)root@nofan:/#
