One thing you can easily do is to add:

void   __crt0_setup_arguments( void ) {}
void   __crt0_load_environment_file( char * unused ) {};

somewhere in the file (or in some file that you link in). This tells the
linker not to bother linking in some functionality you don't use in
"hello world". Obviously in progs that do use that, don't do that...
