another tiny edit for win32

[vadrer]

...also, it would be reasonable to remove such chunks of code at all:

    if (index($link, "Win32CORE") < 0) {
        my $archdir = $ENV{PERL_CORE} ? "../.." : "$Config{archlib}/..";
        my $win32core = "-L$archdir/lib/auto/Win32CORE -lWin32CORE";
        if (-e "$archdir/lib/auto/Win32CORE/Win32CORE.lib") {
            $win32core = "$archdir/lib/auto/Win32CORE/Win32CORE.lib";
        }
        $link .= " $win32core";
    }

reason for existance of such a code is that by default Win32CORE compiled statically into perl executable, However this current workaround is not robust and not equally good across different version of perl.

rather, correct linkage should be coded.

I will prepare such an edit, if you agree
