Bug#1081849: qemu-i386: can't run busybox:i386 on ppc64el: Segmentation fault

Package: qemu-user
Version: 1:9.0.2+ds-2+b1
Severity: normal
User: [email protected]
Usertags: ppc64el

The new cross-exe-wrapper package in src:architecture-properties runs
binaries from a foreign architecture, either directly or via qemu-user.
Its autopkgtest uses busybox from each release architecture (specifically
the `busybox true` and `busybox echo` applets) as a smoke-test to see
whether this works as intended.

On ppc64el, the result indicates that the qemu-i386 in qemu-user:ppc64el
can't run busybox:i386:

> 137s qemu: uncaught target signal 11 (Segmentation fault) - core dumped

I don't know whether this is specific to busybox, or whether the qemu-i386
in qemu-user:ppc64el doesn't work more generally.

architecture-properties (>= 0.2.2) works around this by skipping its
self-test on architecture pairs where qemu-$arch doesn't run successfully.
