* common.mk (main): split from exts and makes main program after

building exts with miniruby, to get rid of overwriting running
  program.  [ruby-core:22339]

* Makefile.in, win32/Makefile.sub (RUNCMD, MKMAIN_CMD): macros to
  run script file.

* ext/extmk.rb (parse_args): added --command-output option which
  creates script file to make main program.
