This patch introduces the framework I've been using in coreutils
for ages.  It helps enforce some of the little nit-picking rules
that we don't like to think about day-to-day, but that really
do matter in some contexts.

Currently, a lot of the tests are not relevant.
A few failed, and I added their names in Makefile.cfg's
list of tests to skip.

For example, the change after this one reenables the
po-check test.  The po-check rule ensures that each source
files using _() is listed in po/POTFILES.in.  As you'll see
in the next patch, a bunch were missing, so translators never
had an opportunity to write translations for messages in those files.
-----------------------------------------------------

Add infrastructure for more rigorous "make distcheck" rules.

From: Jim Meyering <[EMAIL PROTECTED]>

* GNUmakefile: New file.
* Makefile.am (MAINTAINERCLEANFILES): Remove names of files now in build-aux/.
(distcheck-hook): New rule, to run the checks in Makefile.maint.
* Makefile.maint: New file.  Improved "make distcheck" rules.
* Makefile.cfg: Select which Makefile.maint checks to run.
(local-checks-to-skip): List all currently-failing and irrelevant
tests here.
* build-aux/vc-list-files: New file.  List version-controlled files.
* .gitignore: Remove build-aux, since now it contains a
version-controlled file.
