Yes, but please bear in mind that this *only* happens when you have a
machine with huge RAM.  For other people with small RAM, the link
itself is an important factor.  Also, other people have found that the
libtool script consumes a smaller part of total execution time: rth's
measurements are at one extreme of the scale.
