No it's probably from all the libc _start code that is executed. Even if main() is a single line there is much more code that is included in the binary to setup the environment properly, get the arguments in order, see if the terminal is character or line buffered, etc. You should be able to convince the linker to not include all of this -fno- builtin, but you'll need to define a _start symbol.
