Actually, neither autoconf nor automake touches MKINSTALLDIRS; it is all
provided by gettext.  Did you test with gettext 0.14, automake 1.9.6 and
autoconf 2.59?

That's a true statement.  But doesn't automake/autoconf provide some
magic to make it track the correct number of ../ components to be
properly relative through subdirectories?  In other words, what breakage
are you fixing?

claimed that we need something here.  Looking at the gettext history,
here is what gettext used, prior to retiring usage of MKINSTALLDIRS:

-AC_DEFUN([AM_MKINSTALLDIRS],
-[
-  dnl Tell automake >= 1.10 to complain if mkinstalldirs is missing.
-  m4_ifdef([AC_REQUIRE_AUX_FILE], [AC_REQUIRE_AUX_FILE([mkinstalldirs])])
-  dnl If the AC_CONFIG_AUX_DIR macro for autoconf is used we possibly
-  dnl find the mkinstalldirs script in another subdir but $(top_srcdir).
-  dnl Try to locate it.
-  MKINSTALLDIRS=
-  if test -n "$ac_aux_dir"; then
-    case "$ac_aux_dir" in
-      /*) MKINSTALLDIRS="$ac_aux_dir/mkinstalldirs" ;;
-      *) MKINSTALLDIRS="\$(top_builddir)/$ac_aux_dir/mkinstalldirs" ;;
-    esac
-  fi
-  if test -z "$MKINSTALLDIRS"; then
-    MKINSTALLDIRS="\$(top_srcdir)/mkinstalldirs"
-  fi
-  AC_SUBST(MKINSTALLDIRS)
-])

Maybe the real fix for the problem you seem to be seeing is to repeat
more of the body of this (now-obsolete) gettext macro, in the case that
we are still targetting older gettext 0.14.
