build: lower gettext requirements.

Bison was uselessly requiring the formatstring macros from
gettext, which resulted in mo files not being installed on systems
that perfectly supported Bison mo files.  Lower the requirement.
http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html

	* configure.ac: Require need-ngettext instead of
	need-formatstring-macros.
	Reported by Martin Jabocs.
	Suggested by Bruno Haible.
	* INSTALL: Restructure.
	(Internationalization): New.
(cherry picked from commit b9e42bb439643b6b193ba44696c370bbb35d2ec0)

 This package contains the GNU Bison parser generator.
 
-See the file INSTALL for generic compilation and installation instructions.
+* Installation
+** Build
+See the file INSTALL for generic compilation and installation
+instructions.
 
+Bison requires GNU m4 1.4.6 or later.  See:
+
+      ftp://ftp.gnu.org/gnu/m4/m4-1.4.6.tar.gz
+
+** Internationalization
+Bison supports two catalogues: one for Bison itself (i.e., for the
+maintainer-side parser generation), and one for the generated parsers
+(i.e., for the user-side parser execution).  The requirements between
+both differ: bison needs ngettext, the generated parsers do not.  To
+simplify the build system, neither are installed if ngettext is not
+supported, even if generated parsers could have been localized.  See
+http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html for
+more details.
+
+* Questions
 See the section FAQ in the documentation (doc/bison.info) for
 frequently asked questions.  The documentation is also available in
 PDF and HTML, provided you have a recent version of Texinfo installed:
 run "make pdf" or "make html".
 
-Bison requires GNU m4 1.4.6 or later.  See:
-
-ftp://ftp.gnu.org/gnu/m4/m4-1.4.6.tar.gz
-
-Bison can work with pre-1.4.6 distributions of GNU m4 if they are
-sufficiently patched, but if you encounter a bug with an older
-distribution and report a bug we will probably suggest that you
-upgrade to 1.4.6 as the first step in trying to fix it.
+If you have questions about using Bison and the documentation does
+not answer them, please send mail to <help-bison@gnu.org>.
 
+* Bug reports
 Please send bug reports to <bug-bison@gnu.org>.  Please include the
 version number from `bison --version', and a complete, self-contained
 test case in each bug report.
