AM_WITH_NLS fails to find version of bison 1.29

[Pavel Roskin]

Hello!

The AM_WITH_NLS macro from gettext.m4 tries to determine the version of
GNU Bison.  It works with Bison 1.28, but not with Bison 1.29.

The output of "bison --verison" has changed.  Now there is no space after
"GNU Bison"

$ bison --version
bison (GNU Bison) 1.29

This patch against CVS version of gettext fixes the problem.

ChangeLog:

        * m4/gettext.m4 (AM_WITH_NLS): When checking bison version, don't
        require a space after "GNU Bison".  This fixes detection of GNU
        Bison 1.29.
