trace: fix tcg tracing build breakage
Commit 0ab8ed18a6fe98bfc82705b0f041fbf2a8ca5b60 ("trace: switch to modular code generation for sub-directories") forgot to convert "tcg" trace events to the modular code generation approach where each sub-directory has its own trace-events file. This patch fixes compilation for "tcg" trace events. Currently they are only used in the root ./trace-events file. "tcg" trace events can only be used in the root ./trace-events file for the time being. Reported-by: Peter Maydell <peter.maydell@linaro.org> Tested-by: Emilio G.
