The reason I did it like this was that
my getopt_long is really a wrapper around getopt(). That means 
module-init-tools cannot use --long-arguments. My getopt long is only a 
hack in order to port module-init-tools to klibc. Now consider also:
getopt lives <unistd.h> while getopt_long in
#define _GNU_SOURCE
#include <getopt.h>

If I give klibc a getopt.h I should also give it a real getopt_long() 
implementation which I haven't provide. That's why I pushed this 
ugliness to module-init-tools instead. Programs IMO can use quick & 
dirty hacks to achieve short term portability but giving klibc a 
getopt_long that is not really functional would be a mistake.
