This is true. That was something I forgot to mention. I have looked
at that as well, and it strikes me as even more of a hack than the
solutions I mentioned: it is yet another external shell process for
each invocation of Rules.make (ie each directory). As I said before,
though, one man's hack is another man's clean design, so whatever.

Your function is rather long; try this one instead (untested):

remove_duplicates () {
for i; do
case "$str " in *" $i "*) ;; *) str="$str $i" ;; esac
echo "$str"

I still think anything outside the makefiles that's needed to organize
the build process is a hack. That includes scripts/ (yes, I
do have a scheme to get rid of it) and 2.2.18 scripts/kwhich (yes, I
did propose a working alternative). It doesn't include scripts/mkdep.c
(which must do a lot of work as efficiently as possible),
scripts/Configure et al (which are really standalone programs), or
scripts/split-include.c (which is really a continuation of Configure).
