没用过 dumper，不过我印象中是默认开启的吧？

./configure 的时候可以试试下面的选项：

--with-pdumper=VALUE    enable pdumper support unconditionally ('yes', 'no',                                                                                           
                          or 'auto': default 'auto')                                                                                                                                                                                                                               
--with-dumping=VALUE    kind of dumping to use for initial Emacs build                                                                                                 
                          (VALUE one of: pdumper, unexec, none; default                                                                                                  
                          pdumper)             

./configure --with-pdumper=yes
