O wait, I see, it doesn't get defined, we catch the #else:
#if defined(CONFIG_UPROBES) || defined(CONFIG_UPROBES_MODULE)
#include <linux/uprobes.h>
#else
#include "uprobes/uprobes.h"
#endif
[... actual autoconf-test ...]
So, in that case, the correct order of tests seems to be:
#if defined(CONFIG_UPROBES) || defined(CONFIG_UPROBES_MODULE)
/* kernel built-in uprobes found */
#include <linux/uprobes.h>
#else
/* use systemtap local copy, but only if we also have utrace
#if defined(CONFIG_UTRACE)
#include <linux/uprobes.h>
#else
#error "CONFIG_UTRACE not enabled for systemtap uprobes"
#endif
#endif
[... actual autoconf-test ...]
