locale: Allow "" int_curr_Symbol (bug 22294)
The builtin POSIX locale has "" as the international currency symbol, but a non-builtin locale may not have such a blank int_curr_symbol. Therefore to support non-builtin locales with similar "" int_curr_symbol we adjust the LC_MONETARY parser to allow the normal 4-character int_curr_symbol *and* the empty "" no symbol. Anything else remains invalid. Tested by building all the locales. Tested also with a custom C.UTF-8 locale with "" for int_curr_symbol. Signed-off-by: Carlos O'Donell <carlos@redhat.com>
