Fix dtrace commit r37631, it is [Feature #2565]
* 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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37636 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
