Oops. The command

   ./gnulib-tool --create-testdir --dir=../testdir --with-c++-tests 
--without-privileged-tests --single-configure time_rz

now produces this warning and error:

  configure.ac:330: warning: AM_LANGINFO_CODESET is m4_require'd but not 
m4_defun'd
  glm4/locale-fr.m4:140: gt_LOCALE_FR_UTF8 is expanded from...
  configure.ac:30: gl_INIT is expanded from...
  configure.ac:330: the top level
  configure:10166: error: possibly undefined macro: AM_LANGINFO_CODESET

The cause is that every module that has a m4/locale-*.m4 file also needs
the m4/codeset.m4 file, for AM_LANGINFO_CODESET.

This patch fixes it.
