So eventually when we move to 20.11 the same issues may be encountered, maybe that preferable if we are change LTS versions.

I'll proceed with a revert of those 5 patches for now, given 19.11.4 is
already a week late - Christian confirms the build issue is fixed after
doing so.

We can then figure out what the underlinking issue is without urgency
in time for 20.11, and then I'll add the patches again.
