* configure.in: disable dtrace because it doesn't work on FreeBSD.
* common.mk (clean-local): rm probes.h.
* common.mk (parse.o): depend $(PROBES_H_INCLUDES).
* common.mk (.d.h): moved from Makefile.in and use BASERUBY.
* tool/gen_dummy_probes.rb: reimplemented with ruby because sed is not
available on Windows Microsoft VC++ environment.
