The patch removing the feature-sync-compare-and-swap feature detection didn't remove the call to main_test_sync_compare_and_swap(), making the 'test-all' case fail an all the feature tests to be performed individually:

$ cat /tmp/build/perf/feature/test-all.make.output In file included from test-all.c:18: test-libpython-version.c:5:10: error: #error 5 | #error | ^~~~~ test-all.c: In function ‘main’: test-all.c:203:9: error: implicit declaration of function ‘main_test_sync_compare_and_swap’ [-Werror=implicit-function-declaration] 203 | main_test_sync_compare_and_swap(argc, argv); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors $

Fix it, now to figure out what is that test-libpython-version.c problem...
