[RFA] ARI fix: linux-nat.c: remove strlen d_name

["Pierre Muller" <muller@ics.u-strasbg.fr>]

  Here also, I could have used the obvious rule,
but I am still not really sure about the
ChangeLog entry.
  I was unable to find the proper way to tag
a ChangeLog entry for Awk Regression Index.

  Does anyone remember?

  Is this OK to commit?
