    BaseTools: Update BaseTools top GNUMakefile with the clear dependency
    
    https://bugzilla.tianocore.org/show_bug.cgi?id=786
    
    After GNUmakefile dependency is fixed up, it can make with -j N to enable
    multiple thread build in base tools C source and save build time.
    
    In my linux host machine, make -j 4 to compile BaseTools and save ~60% time.
