FYI: another tiny closeout.c change

[Jim Meyering]

I've just done this in coreutils, in case EBADF is not
defined on some system.  Do any of you know of a system
(reasonable porting target) for which <errno.h> does not define EBADF?

        * closeout.c (EBADF): Fail with `#error ...' if it's not defined,
        asking the user to report the problem.
