Subject: [for-linus][PATCH 2/4] tracing/boot: Fix config dependency for synthedic event

From: Masami Hiramatsu <mhiramat@...nel.org>

Since commit 726721a51838 ("tracing: Move synthetic events to
a separate file") decoupled synthetic event from histogram,
boot-time tracing also has to check CONFIG_SYNTH_EVENT instead
of CONFIG_HIST_TRIGGERS.
