speed up building with less disk IO pod moves+__END__+misc

In Cwd.pm, dont search for pwd on Win32.

Also trim down the list of makefile suffixes on Win32 so it doesn't try
searching for av.pas and perl.f90 and hash.cbl on disk.

Add __END__ tokens to stop the last read() call on the handle which
returns 0 bytes at EOF.
