  New Revision: 62245

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=62245

  Log:
    mjit headers for universal binary
    
    * common.mk (MJIT_HEADER, MJIT_MIN_HEADER): added hook to separate
      intermediate headers per archs.
    
    * defs/gmake.mk: build mjit headers per -arch options, and then
      merge the headers with `#ifdef`s.
