PA glibc nls bug

In the following test program, the call to nl_langinfo_l returns an
incorrect wchar_t string.  We are dropping the first two wide chars:
0x0000897f 0x00005143.  You can see the difference by running this
test on x86 and parisc under gdb, or by printing pp.

#include <locale.h>
#include <langinfo.h>
#include <wchar.h>
wchar_t *
foo (void)
{
  char *__s = "zh_TW";
  wchar_t *pp;
  locale_t loc;
  union { char *__s; wchar_t *__w; } __u;

  loc = newlocale(1 << LC_ALL, __s, 0);
  __u.__s = nl_langinfo_l(_NL_WD_FMT, loc);
  pp = __u.__w;
  return pp;
}
int
main ()
{
  wchar_t *pp;
  pp = foo ();
  return 0;
}

This problem breaks locale support in libstdc++.

I didn't notice this until recently because I didn't have all the locales
needed for the libstdc++ testsuite.  So, the tests using named locales
were skipped.

It's easy to add the necessary locales.  Just add the following to
/etc/locale.gen:

# For libstdc++
de_DE ISO-8859-1
de_DE@euro ISO-8859-15
en_HK ISO-8859-1
en_PH ISO-8859-1
es_ES ISO-8859-1
es_MX ISO-8859-1
fr_FR ISO-8859-1
fr_FR@euro ISO-8859-15
is_IS ISO-8859-1
is_IS.UTF-8 UTF-8
it_IT ISO-8859-1
ja_JP.EUC-JP EUC-JP
se_NO UTF-8
ta_IN UTF-8
zh_TW BIG5
zh_TW.UTF-8 UTF-8
zh_TW.EUC-TW EUC-TW

Then, make the locales available using locale-gen.
