Subject: [PATCH/RFC] perf tools: Make GTK2 support opt-in
This is bitrotting, nobody is stepping up to work on it, and since we
treat warnings as errors, feature detection is failing in its main,
faster test (tools/build/feature/test-all.c) because of the GTK+2
infobar check. So make this opt-in, at some point ditch this if nobody
volunteers to take care of this.

Now to check the next test-all.c failure:
[acme@...e perf]$ cat /tmp/build/perf/feature/test-all.make.output
/usr/bin/ld: /tmp/ccywyyOR.o: in function `main_test_libzstd':
/home/acme/git/perf/tools/build/feature/test-libzstd.c:8: undefined reference to `ZSTD_createCStream'
/usr/bin/ld: /home/acme/git/perf/tools/build/feature/test-libzstd.c:9: undefined reference to `ZSTD_freeCStream'
collect2: error: ld returned 1 exit status
[acme@...e perf]$
Probably just a lack of -Lzstd to the test-all target...
