Sure you link your object file with your own instead of using
the default....

gcc -c -o myprog.o myprog.c
as -o start.o start.S

ld -o myprog myprog.o start.o /lib/libc.so.6
| | |___ runtime lib
| |__________________ Your startup
|__________________________ Your program

Startup starts with a label _start. You may have to write it
in assembly. It calls main() and must never return. Instead
it calls exit() with whatever main() returned, to quit.

__init() is some M$ thing. Linux executables start with
_start().
