init_local_tick initializes the 'local_tick' global variable that
is directly accessed from coverage.c.

Hi,
Most compiler invocations don't actually need an entropy source, so
open-read-close syscall sequence on /dev/urandom that GCC performs on
each startup is useless (and can easily be avoided).
This patch makes GCC read entropy from /dev/urandom lazily on first
call to get_random_seed, and en pa
