Looks like this make command is not being run from the same directory as
the makefile, or perhaps "makefile" is misspelled?  Can you build
examples in-place within the source tree?

  $ cd src/sys/examples/tutorials
  $ make ex2

Then go back to the directory containing your files (ex2.c and makefile)
and try

  $ make -f makefile ex2

You can trim it down to the minimal makefile like Matt suggested, though
this should not change anything.
