 Branch u/cpernet/fflas_and_linbox_broken_with_gcc_8_1_0 deleted
I agree with the proposed fixes for fflas given here and the simple removal of the double template proposed on sagedevel by fidelbc and Dario Asprone. I have fixed both libraries upstream and add the corresponding patches to the branch for this ticket.
