	Make it possible for multiple threads to use gettext() in different
	locales.
	* intl/dcigettext.c (HAVE_PER_THREAD_LOCALE): New macro.
	(struct known_translation_t): If HAVE_PER_THREAD_LOCALE, add localename
	field.
	(transcmp): If HAVE_PER_THREAD_LOCALE, compare localename fields.
	(DCIGETTEXT): If HAVE_PER_THREAD_LOCALE, fill the localename field in
	search and newp.

	* intl/tst-gettext4.c: New file.
	* intl/tst-gettext4.sh: New file.
	* intl/tst-gettext4-de.po: New file.
	* intl/tst-gettext4-fr.po: New file.
	* intl/tst-gettext5.c: New file.
	* intl/tst-gettext5.sh: New file.
	* intl/Makefile (distribute): Add tst-gettext4.sh, tst-gettext4-de.po,
	tst-gettext4-fr.po, tst-gettext5.sh.
	(multithread-test-srcs): New variable.
	(test-srcs): Add its contents.
	(tests): Depend on tst-gettext4.out, tst-gettext5.out.
	(tst-gettext4.out, tst-gettext5.out): New rules.
	(CFLAGS-tst-gettext4.c, CFLAGS-tst-gettext5.c): New variables.
	Add rule for linking the multithread-test-srcs with the appropriate
