Control: tags -1 + patch Hi,
I got a build going through on armhf with the below workaround,
in which I used indications from ArchitectureSpecificsMemo[1]
to reroute the code to safe fallbacks on armhf as well as armel,
without affecting arm64:

Then I learned about #1068872, so I stopped whatever testing I
had planned (interference of the patch on other archs, maybe
installing the package to make sure it has no obvious defects,
that sort of things). The patch is available in case one wants
to take over from here.
