Comment 9 for bug 1707409

I agree on 384 being getrandom and there are other cases like [1].
I don't know details but would consider the pure lack of the system call support a feature request to upstream qemu.
We could add a qemu upstream task here for that FR - in the worst case we are told why we are wrong - opinions?

On the case itself for now I'd recommend to get back the section:
ifeq ($(DEB_HOST_ARCH),armhf)
        TERM=vt100 dh_auto_test || true

Which maybe was there for similar reasons.
