We were failing that due to GTK2+ and then for the ZSTD test, which made
test-all.c, the fast path feature detection file to fail and thus
trigger building all of the feature tests, slowing down the test.
Eventually the ZSTD test would be built and would succeed, since it had
the needed -lzstd, avoiding:
$ cat /tmp/build/perf/feature/test-all.make.output
/usr/bin/ld: /tmp/ccRRJQ4u.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
$
Fix it by adding -lzstd to the test-all target.
Now I need an entry to 'perf test' to make sure that
/tmp/build/perf/feature/test-all.make.output is empty...
