Yes, Plan 9 from User Space (which provides the ports of Plan 9
utilities to Unix-like systems) provides an ls binary that is
incompatible with what Emacs expects.

It would be a great deal of trouble to support their version of ls (and
indeed, their versions of many other common Unix utilities such as `rm'
and `cp'), so I think the answer is simply "don't run Emacs with
plan9/bin at the head of your PATH".
