exitfail

[Simon Josefsson]

There is also this warning:

gnulib-tool: warning: module obstack depends on a module with an incompatible 
license: exitfail

The exitfail.h is:

extern int volatile exit_failure;

and exitfail.c is:

#include <config.h>
#include "exitfail.h"
#include <stdlib.h>
int volatile exit_failure = EXIT_FAILURE;

Is this worth having the GPL on?  Assuming it is even copyrightable, it
seems rather trivial to me.  Any objections to relaxing the license to
at least LGPLv2.1+?

Further, exitfail.m4 is:

AC_DEFUN([gl_EXITFAIL],
[
  AC_LIBOBJ([exitfail])

  dnl No prerequisites of lib/exitfail.c.
  :
])

It seems this file could be dropped, and the AC_LIBOBJ moved to
modules/exitfail.

See patch below.
