You can see an explanation in svn log:

Update this file so that BIND on ARM can actually work. I quote:

        The problem was, isc_atomic_cmpxchg() is almost like our
        atomic_cmpset_32(), except it expects the old value to be
        returned, whereas our atomic_cmpset_32 returns 1 on success,
        or 0 on failure. So I re-implemented something suitable.

Add a custom atomic.h file which implements the C versions of the
code we already have assembly versions of.
