Produce a clean failure in configure when dtrace is selected but cannot be
found. Besides stopping those early who have no dtrace installedwhatsoever, this will also alert those who have dtrace in /usr/sbin, whichmight not be in the path, which would produce confusing failures much laterin the build process.Add documentation about pointing configure to find dtrace.
