[PATCH v1 11/13] perf build: If libtraceevent isn't present error the build

[Ian Rogers]

If libtraceevent isn't present, the build will warn and continue. This
disables a number of features and so isn't desirable. This change
makes the build error for this case. The build can still be made to
happen by adding NO_LIBTRACEEVENT=1.
