  regex: work around conditional-dependencies glitch
  
  * modules/regex (Depends-on): Add langinfo.
  Without this change, I had problems building an experimental
  version of GNU Emacs.  The symptom of the bug was a message
  ‘./configure: line 12726: test: =: unary operator expected’.
  This was due to a line in gl_FUNC_NL_LANGINFO that invokes
  ‘test $HAVE_LANGINFO_CODESET = 1’ even though HAVE_LANGINFO_CODESET
  was unset.  Although gl_FUNC_NL_LANGINFO has
  ‘AC_REQUIRE([gl_LANGINFO_H])’ and gl_LANGINFO_H always sets
  HAVE_LANGINFO_CODESET to 0 or 1, gnulib-tool with
  --conditional-dependencies sometimes arranges for the
  gl_FUNC_NL_LANGINFO code to be executed before the gl_LANGINFO_H
  code.  Since the regex code includes <langinfo.h> it should be
  depending on the langinfo module anyway, and this happens to work
  around the bug, so install that as a workaround for now.  To
  reproduce the original problem, run the following shell script on
  the version of Gnulib just before this patch was installed.
  	rm -fr foo
  	mkdir foo
  	cat >foo/configure.ac <<'EOF'
  	AC_INIT(GNU Emacs, 27.0.50, bug-gnu-emacs@gnu.org, , https://www.gnu.org/software/emacs/)
  	gl_EARLY
  	gl_INIT
  	AC_OUTPUT
  	EOF
  	./gnulib-tool --import --conditional-dependencies --gnu-make --dir foo regex
  	./gnulib-tool --copy build-aux/install-sh foo/install-sh
  	./gnulib-tool --copy build-aux/config.sub foo/config.sub
  	./gnulib-tool --copy build-aux/config.guess foo/config.guess
  	cd foo
  	aclocal -I m4
  	autoconf
  	./configure --with-included-regex
