gst-plugin-x170: we've removed it now.

log4cpp builds OK.

sdbusplus indeed fails, and it is not trivial to fix. I have a solution,
but it is ultimately ugly, which implies either we're in deep sh!t, or I
missed something obviously obvious (I'd bet on the latter).

Which means that libsigrok may have the same issue as sdbusplus... I'll
try to come up with something saner for bot

I did not even dare look into asterisk for now...
