commit de383203d4d7921bf331510bc898ab88c5844731
Author: Evgeny Grin (Karlson2k) <k2k@narod.ru>

    Reworked dlltool supported.
    
    * Added support for weakened oversimplified half-broken llvm-dlltool
    * Streamlined makefile receipts for W32 .dll and related files
    * Added support for verbose/silent makefile rules
    * Removed redundant printing from makefile
    * Added makefile receipts for proper generation of all required files
    * Silenced MS lib warning
    * Silenced MS lib invocation
