[Bug-tar] tar-1.13.90: i18n broken

[Bruno Haible]

Hi,

In a German locale, "tar --help" prints its output in English. It doesn't
even attempt to open the German message catalog. The reason is that the
'tar' program never attempts to call
     setlocale (LC_ALL, "");
Although this line of code is present in tar.c at the right place, it has
no effect: system.h defines setlocale to empty, because configure.ac is
missing an AC_CHECK_FUNCS(setlocale) call.
