So here my status.
it was possible to perform: "sudo apt build-dep octave", it installed 104 packages.
Then I have run "./bootstrap" & "./config ... ..." then
"nice -n 19 make JOBS=8 hg-octave-dist hg-octave-branch=stable"
It informed me about the missing "octave-6.0.1.tar.lz".
I repeated the "nice [...]"command once more.
To get rid of this message I tried a command I found on the page mentioned by Markus, but I modified the command.
"make dist-lzip DIST_IGNORE_HG_STATE=1"
failed, there is no rule for "dist-lzip".
"make dist DIST_IGNORE_HG_STATE=1" worked fine.
I copied the "mxe-octave-a65cacd05892.tar.gz" into my build directory.
And tried again, now I see: "Unknown option 'qt5'"
