eventfd.2, mprotect.2, pidfd_open.2, spu_run.2, timer_create.2, bswap.3, dl_iterate_phdr.3, endian.3, pthread_attr_init.3, pthread_getattr_np.3, vcs.4, rtld-audit.7: In printf(): s/0x%/%#/ except when followed by X instead of x 

Use printf()'s '#' flag character to prepend the string "0x".

However, when the number is printed in uppercase, and the prefix
is in lowercase, the string "0x" needs to be manually written.
