Clang will complain if main() is not declared with 0, 2, or 3 arguments. In order to allow an extra 4th parameter, a new weak main() symbol which just jumps to driver_main is defined, and _start passes the extra init pointer to main. Additionally, libc's crt0.s _start is made weak, and a matching _libc_crt0_start symbol is defined for implementations that wish to override _start but still call libc's _start. (Will be used by init.)
