Description of problem:

Given this tiny program:

        #include <time.h>

        int main () {
                struct timespec t;
                clock_gettime(CLOCK_BOOTTIME, &t);
                return 0;
        }

strace prints "0x7 /* CLOCK_??? */" instead of CLOCK_BOOTTIME

Version-Release number of selected component (if applicable):
   strace-4.8-1.fc20.x86_64


How reproducible: every time


Steps to Reproduce:
1. Compile the tiny program above
2. strace -e clock_gettime ./a.out
3. Observe clock_gettime system call

Actual results:

   clock_gettime(0x7 /* CLOCK_??? */, {17973, 83774407}) = 0


Expected results:

   clock_gettime(CLOCK_BOOTTIME, {17973, 83774407}) = 0

Additional info:

I've attached a proposed patch, but strace itself doesn't build with the current kernel and headers (some different problem I've not looked into).  The patch itself is trivial though.
