S for the compiler avr-gcc but I did find a crt1. S and the same with the corresponding. What is the difference between these two files? Is crt1 something completely different or what?

They both seem to have to do with something for 'bootstrapping' setting up stack frame and such , but why the distinction? You should link with one or the other but not both. They are not really libraries but really inline assembly code.
