bricks: ATOMIC_FLAG_INIT initialization

Browse source 
From the working draft: "The macro ATOMIC_FLAG_INIT shall be defined
in such a way that it can be used to initialize an object of type
atomic_flag to the clear state. The macro can be used in the form:
atomic_flag guard = ATOMIC_FLAG_INIT; It is unspecified whether the
macro can be used in other initialization contexts."
