Back when I sent a libedit upgrade patch, before obrien update libedit on his
own, I managed to build the whole tree with libedit, gdb, ntpc and others were
fully functionnal with it, (at that time I totally removed libreadline)

The only "problem" I see is from the ports lots of them relies on base
libreadline, so we need to first run an exp-run without libreadline, to
determine the impact and fix the related ports, before we can fully dropped
libreadline.
