ui/gtk/annotate.c: In function ‘symbol__gtk_annotate’:
ui/gtk/annotate.c:177:44: error: ‘annotation__default_options’ undeclared (first use in this function); did you mean ‘annotation_options’?
  177 |         err = symbol__annotate(ms, evsel, &annotation__default_options, NULL);

      |                                            annotation_options
ui/gtk/annotate.c:177:44: note: each undeclared identifier is reported only once for each function it appears in
make[6]: *** [/var/home/acme/git/perf-tools-next/tools/build/Makefile.build:97: ui/gtk/annotate.o] Error 1

I'll fix this later...
