[PATCH] Fix ld-time.c

[Jakub Jelinek <jakub at redhat dot com>]

Hi!

wformat and wname fields are used in:
      iov[2 + cnt].iov_base = (void *) time->era_entries[num].wname;
      iov[2 + cnt].iov_len = ((wcschr ((wchar_t *) time->era_entries[num].wformat, L'\0')
                               - (wchar_t *) time->era_entries[num].wname + 1)
                              * sizeof (uint32_t));
so, clearly neither should be NULL and both have to be in the same object.
The following patch attempts to do whatever we do for narrow name/format
(except the verbose warnings), i.e. if at least one of them is unspecified,
both are set to empty strings.

	* locale/programs/ld-time.c (time_finish): If wide era name or
	format aren't provided, set both wname and wformat to L"".
