#include <sys/prctl.h> is the documented way for getting the prototype 
of prctl(), which cannot be in linux/prctl.h for obvious reasons.

This patch creates the following problem:

../strace-4.26/strace.c: In function 'startup_child':
../strace-4.26/strace.c:1355:3: warning: implicit declaration of function 'prctl' [-Wimplicit-function-declaration]
   prctl(PR_SET_PTRACER, PR_SET_PTRACER_ANY);
