Ah right.

I understand autoconf/automake/libtool have problems with filenames with
spaces in, though that's really not an argument for making things worse.

As you suggested, "2> /dev/null" would hide the message.  Or if that seems
unclean, the rm could be split into two (perhaps for a small performance
penalty in that rm gets run twice in one case):

rm -f "foo.o"
test -z "$foo_objs" || rm -f "$foo_objs"

Or use an if to handle the two cases:

if test -z "$foo_objs" ; then
  rm -f "foo.o"
else
  rm -f "foo.o" "$foo_objs"
fi

Cheers,
