Subject: [PATCH 0/2] fix perf tool build error on MUSL libc

__always_inline can cause build error on musl libc because it's not
defined. We need to include <linux/stddef.h> before asm/byteorder.h.
tools/include/uapi/linux/perf_event.h is copied version from
include/uapi/linux/perf_event.h. To fix this, we need to apply this
change both header files.
