hmm. Could you check the config.log if video was enabled? Maybe the configure
decided that video was disabled but we still build that file...

Well, the problem is more with the .Po and .Plo files. If half the files
contain '#dummy' it will probably still be a lot faster, if all of them
contain the dependencies it will be a lot slower (at least for me).

My desktop is still in a container on some boat and I am stuck with my lower
end laptop.

Is there anything I can help with? bisect GNU make 3.81 -> 3.82 to see when it
got slower? Or anything on our GNU make/automake usage? E.g. we use a non
recursive makefile
