it did run overnight... but seems fine for now. So now I don't get into 
a dependency loop. Interestingly, that fixed also gcc6
Wonder what was wong? There were no outdated gcc/libgcc ports, both were 
still installed.

Then, well there are issues compiling xz-bootstrap itself with gcc 6, 
7... but not with 4.8! amazing.
