When using constructor methods they do not get argv and argc.
Following code extract is working on standard glibc, but gives coredump on
uClibc.
Untill fixed I will use /proc/self/cmdline.

Example:
static void program_environment(int argc, char **argv, char **envp)
__attribute__ ((constructor (100)));

static void program_environment(int argc, char **argv, char **envp) 
{
    int c;
    static struct option long_options[] = {
        {"help", 0, 0, 'h'},
        {"version", 0, 0, 'v'},
        {0, 0, 0, 0}
    };

    opterr = 0;
    optind = 0;

    while (1)
    {
        int option_index = 0;

        c = getopt_long(argc, argv, arguments, long_options, &option_index);

        if (c == -1) break;

        switch (c) {
        case 'h':
            program_help = true;
            break;
        case 'v':
            program_version = true;
            exit ( 0 );
        default:
            break;
        }
    }
}

int main(int argc, char **argv, char **envp) 
{
    program_help = false;
    while (1)
    {
        sleep(10);
    }
}
