If you did that then the configure script would likely only work on 
your system.  If it only runs on your system, what's the point?

Libtool is for portably creating libraries.  If you only plan to 
create libraries that work on your own computer, then you can 
hard-code everything in a Makefile and skip using libtool.

Regardless, libtool 2.2 and latter has been shown to have minimal 
impact on build times.
