    libstdc++: Fix configuration of default zoneinfo dir on linux
    
    The config for --with-libstdcxx-zoneinfo=yes was comparing the target
    triplet to "gnu* | linux* | kfreebsd*-gnu | knetbsd*-gnu" which is only
    the last component of the triplet, so failed to match and always used
    the zoneinfo_dir=none default. Check $target_os instead.
    
    There was also an error in the check for native builds that tzdata.zi is
    actually present in the configured directory. That meant a warning was
    printed even when the file was present:
    
    configure: zoneinfo data directory: /usr/share/zoneinfo
    configure: WARNING: "/usr/share/zoneinfo does not contain tzdata.zi file"
    configure: static tzdata.zi file will be compiled into the library
    
    libstdc++-v3/ChangeLog:
    
            * acinclude.m4 (GLIBCXX_ZONEINFO_DIR): Check $target_os instead
            of $host. Fix check for file being present during native build.
            * configure: Regenerate.
