Bug#913077: RM: gjs [s390x] -- RoM; now requires mozjs60 which fails tests on s390x

[Simon McVittie]

Package: ftp.debian.org
Severity: normal
Control: block 906016 by -1

Since upstream version 1.54, gjs requires mozjs60, which has not been
built successfully on s390x (around 80% of its build-time tests fail).
The release team have indicated (on #906016) that they consider it
to be reasonable to drop gjs and its (recursive) reverse-dependencies
from s390x.

This requires removal of s390x binaries from the following source
packages:

cortina
eos-sdk
gdm3
gjs
gnome-applets
gnome-characters
gnome-documents
gnome-initial-setup
gnome-maps
gnome-panel
gnome-shell
gnome-shell-mailnag
gnome-shell-pomodoro
gnome-sushi
meta-gnome3
polari
sensors-applet
xfswitch-plugin

of which cortina is already up for removal on all architectures (#910599).

`dak rm` thinks these would also be broken, but these appear to be false
positives:

gnome-sound-recorder (Arch: all)
gnome-terminal ([!s390x])
gnome-weather (Arch: all)
gpaste (Arch: all)
libguestfs ([!s390x])
libsecret ([!s390x])
seed-webkit2 (never built on s390x)
workrave ([!s390x])

Thanks,
