elf_end(): rwlock_fini() with a locked object

[Kurt Roeckx <kurt at roeckx dot be>]

Hi,

In libelf/elf_end.c:244 you have:
  rwlock_fini (elf->lock);

But this lock is always still held when you get there.

I see this:
>  Results are undefined if pthread_rwlock_destroy()
>  is called when any thread holds rwlock.
[...]
>       The pthread_rwlock_destroy() function may fail if:

And I get this on Debian's kfreebsd port, resulting in an
assertion failure.  I wonder why I'm not getting it on other
ports.

Adding a "rwlock_unlock (elf->lock);" just in front of that
line fixes the problem.
