+Subject: [PATCH] Fix autoconf detection of perf_events
+
+The autoconf check for the presence of perf_events api began failing
+on recent openSUSE builds.
+
+checking kernel supports perf_events... conftest.c: In function 'main':
+conftest.c:37:39: error: implicit declaration of function 'getpid' [-Wimplicit-function-declaration]
+   37 |                                 pid = getpid();
+      |                                       ^~~~~~
+conftest.c:38:33: error: implicit declaration of function 'syscall' [-Wimplicit-function-declaration]
+   38 |                                 syscall(__NR_perf_event_open, &attr, pid, 0, -1, 0);
+      |                                 ^~~~~~~
