dlopen fails from static binary

[Emmanuel Dreyfus <manu%netbsd.org@localhost>]

Hi

On netbsd-6, using dlopen in a static binary will return NULL without 
setting errno.

It seems wrong. Is dlopen really supposed ot fail when called from 
static binary? In that case errno should be set, but to what value?
Or perhaps we could support dlopen from static binary?

Example program:

$ cat test.c                                                                   
#include <stdio.h>
#include <dlfcn.h>
#include <errno.h>
#include <err.h>

int
main(void)
{
        void *dlh;

        errno = 0xdeadbeef;
        dlh = dlopen("/usr/lib/security/pam_unix.so.3", RTLD_NOW);
        if (dlh == NULL)
                err(1, "dlopen failed");

        printf("success (%p)\n", dlh);
        return 0;
}
$ cc -o test test.c && ./test
success (0xbbbea800)
$ cc -static -o test test.c && ./test
test: dlopen failed: Unknown error: 3735928559
