On z/OS, set a charset tag on iconv's output file. For the concept of charset tags as external metadata on z/OS files, see <https://lists.gnu.org/archive/html/bug-gnu-libiconv/2023-04/msg00021.html>. * src/zos-tag.h: New file. * src/iconv.c: Include zos-tag.h. (convert): Add a 'tocode' parameter. On z/OS, turn off auto-conversion and tag the output file. (main): Update callers. * tests/check-ebcdic: On z/OS, make all test files initially untagged. * tests/check-tag: New file. * tests/Makefile.in (check): Pass the host_os to check-ebcdic. Invoke check-tag.
