I didn't for a while (but succeed in past).

Anyway I tried to revert the change and it opens a can of worms. The
initial fix I ended needing to work was to fix QEMU call and this,
after some scratch head worked. However this didn't fix the build as
QEMU eats a lot of memory doing the processing and eventually is
killed:

[1673545.675672] Out of memory: Kill process 22041 (qemu-arm) score
960 or sacrifice child
[1673545.675963] Killed process 22041 (qemu-arm) total-vm:31542644kB,
anon-rss:31482564kB, file-rss:1368kB

So this is very frustrating ...
