        * libc/posix/opendir.c (opendir): Change code to check
        for HAVE_FCNTL before calling fcntl.
        * libc/search/hash.c (hash_open): Ditto.
        * libc/search/hash_page.c (open_tmp): Ditto.
        * libc/reent/Makefile.am: Add fcntlr.c.
        * libc/reent/Makefile.in: Regenerated.
        * libc/reent/fcntlr.c: New file.
        * libc/stdio/fdopen.c (_fdopen_r): Change to call _fcntl_r
        instead of _fcntl when HAVE_FCNTL flag is set.
        * libc/syscalls/sysfcntl.c (fcntl): Check for HAVE_FCNTL flag
        to see if _fcntl or _fcntl_r should be called.  If flag is not
        set, default to ENOSYS stub.
