merge revision(s) 49411,49419,49451,49485,49489:

	configure.in: check dtace -G

	* configure.in (RUBY_DTRACE_POSTPROCESS): check if the object file
  is really modified by `dtrace -G`, this command is very system
  dependent.
	* common.mk (ruby-glommed.o): dependency on $(OBJ) should be written
	  in common.mk (in which OBJ is defined) because of Makefile include
	  and parse order. This partly reverts r49419.
	  [ruby-dev:48849] [Bug #10808]

	* Makefile.in (ruby-glommed.o): ditto.

	* Makefile.in (ruby-glommed.o): remove excess $(DTRACE_OBJ) because
	  it is included in $(OBJS) since r49451.

	* Makefile.in (probes.o): should depend on $(DTRACE_DEPENDENT_OBJS)

	* Makefile.in (probes.stamp): rebuild dtrace dependent objects
	  only when `dtrace -G` modifies its input files.
