[perl #36647] 'make languages' should continue after building a language failed

[Jerry Gay via RT]

leo's fix (r8695) works just fine on windows :)

but what is all this .dummy business?

  tcl: tcl.dummy
  tcl.dummy:
        - $(MAKE_C) tcl
  tcl.test:
        - $(MAKE_C) tcl test
  tcl.clean:
        - $(MAKE_C) tcl clean


can't that just be 
  tcl:
        - $(MAKE_C) tcl
etc.
