Subject: [PATCH] perf build: Fix LIBTRACEEVENT_DYNAMIC
The tools/lib includes fixes break LIBTRACEVENT_DYNAMIC as the
makefile erroneously had depdendencies on building libtraceevent even
when not linking with it. This change fixes the issues with
LIBTRACEEVENT_DYNAMIC by making the built files optional.
