I removed gtk4 from FEATURES_DISPLAY, as it is opt-in, no point in
telling most of the time it is OFF, when developing one can use 'make
VF=1' to see if it was detected:

⬢ [acme@toolbx perf-tools-next]$ alias m='rm -rf ~/libexec/perf-core/ ; make VF=1 CORESIGHT=1 -k O=/tmp/build/$(basename $PWD)/ -C tools/perf install-bin && perf test import && cat /tmp/build/$(basename $PWD)/feature/test-all.make.output' ; export PYTHONPATH=/tmp/build/$(basename $PWD)/python
⬢ [acme@toolbx perf-tools-next]$ m
make: Entering directory '/home/acme/git/perf-tools-next/tools/perf'
  BUILD:   Doing 'make -j32' parallel build

Auto-detecting system features:
