we had this workaround some time ago, it was removed by
commit 9ce9ec662ce7b642967fd75222114b624b8a503a

removed re-define of __NR_perf_event_open, what was needed for stale
headers in older kernels. sys/syscall.h will not be correct.
-/* __NR_perf_event_open in ia64 and alpha is defined elsewhere */
-#ifdef __ia64__
-#include <asm-generic/unistd.h>
-#endif
-ss
