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?

Secondly, I wanted to optimize the way gcc is called ? Why does libtool
need to create a shell snippet for all source files ? A Makefile that
simply calls gcc for each source file is much much faster ;))))

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.
