Using the configure script is not needed. Building Git using just a make command can work. You might want to try it and see if it fails as you expect when libcurl4-gnutls-dev is not installed. In the top level Makefile you can see all the variables that can be set to customize the build. These days the configure infrastructure is not as well maintained as the Makefile. Best, Christian.
