Support tracing in config.mk when enabled
Use -finstrument-functions when tracing is enabled (make FTRACE=1). Tracing is not currently supported by SPL even if sufficient memory is available. When tracing is enabled, we #define FTRACE. This can be used by board config files to conditionally enable the tracing options. Signed-off-by: Simon Glass <sjg@chromium.org>
