As someone else said, these scripts are automatically generated from 
'autotools' [1].

The configure / make / make install set of command is an attempt to 
generalize the way of distributing software on *nix boxes.
The bulky script basically tries to 'discover' whats on your machine and 
produce makefiles which are going to successfully build the executable(s) 
on the current architecture, starting from the same source code.

With autotools, you specify some rules (in a file usually called 
configure.ac) which describe what is going to be needed for creating the 
executable, and then the configure script is created automatically, 
tryingto abstract what you requested for every architecture/distro you are 
going to build the executable on.

This in a very short and simplyfied way.

Bye,
Alessandro
