Indeed, I clearly misunderstood its usage pattern. I looked at its source 
("src/port/pg_strong_random.c") where the function is always defined and 
is documented as returning false if it does not find a strong random 
source, so I though that checking for this was enough. But indeed its
compilation fails if no source is provided.

Thanks for the fix.
