No guarantee from me. I will try to keep it simple ;)

I see. Since I always run autoreconf and a new specific libtool is
created during configure run, it should be ok as long as the genrated
libtool does the right thing. This is time consuming and requires
much more interaction than just doing `cp /bin/libtool .`, but it is
safe.
I would vote pro removing the stand alone libtool.

Ok.
