''strace time ls'' will try to run the external command ''time'' which
apparently you haven't got installed.  (Which is probably good in this
case, as it avoided some confusion....)

What you want is:

  strace bash -c 'time ls'

(You may need to give additional options to strace as well, to get the
behavior you want.)

Maybe your libc is broken?  Or your compiler, if all of these are
self-compiled gentoo e-builds?
