external/liblangtag: Avoid null pointer deref in lt_warning call
Recent GCC 10 trunk warns (when LO is configured with --enable-optimized):
> In file included from lt-script-db.c:24:
> lt-script-db.c: In function ‘lt_script_db_parse.constprop’:
> lt-messages.h:105:2: error: ‘%s’ directive argument is null
[-Werror=format-overflow=]
> 105 | lt_message_printf(LT_MSG_WARNING, \
> | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
> 106 | LT_MSG_FLAG_NONE, \
> | ~~~~~~~~~~~~~~~~~~~
> 107 | 0, \
> | ~~~~~~
> 108 | __VA_ARGS__)
> | ~~~~~~~~~~~~
> lt-script-db.c:137:4: note: in expansion of macro ‘lt_warning’
> 137 | lt_warning("No subtag node: description = '%s'",
> | ^~~~~~~~~~
> lt-script-db.c:137:47: note: format string is defined here
> 137 | lt_warning("No subtag node: description = '%s'",
> | ^~
