[PATCH] Ensure AC_CONFIG_FILES, AC_CONFIG_LINKS, and AC_CONFIG_COMMANDS are not prerequisites of `all'.

[Ralf Wildenhues]

* tests/output13.test: New test.
* tests/Makefile.am: Adjust.
Prompted by report from Bruno Haible in
<http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00479.html>.
---

Applied to master and branch-1-10, to address the question:
|   - Is it possible to use AC_CONFIG_FILES conditionally? I.e.
| 
|        if test $gl_cv_stdint_correct = no; then
|          AC_CONFIG_FILES([$sourcebase/stdint.h:$sourcebase/stdint.in.h])
|        fi
| 
|     Will automake do the right thing with this?

Note that for automake it is important whether there are variables in
AC_CONFIG_FILES arguments (like $sourcebase above); see
<http://sources.redhat.com/automake/automake.html#Requirements>
but that is not the main part of Bruno's question.  Anyway I will
address it in a separate mail.

This patch is only to ensure that shell-conditional AC_CONFIG_FOOS work
for FOOS != HEADERS, i.e., that automake won't cause them to be built at
`make' time if config.status has not generated them.

Cheers,
Ralf
