src/usr.sbin/bind/include/isc/platform.h is configured for $have_atomic = "yes" archs(i386, x86_64, sparc, mips...).
but $have_atomic = "no" on some archs.

>How-To-Repeat:
test on evbarm arch
>Fix:
configure bind9.4.1-P1 on evbarm and i386, and check diffs.
I made patch. 
http://world.uraru.net/~a.rin/NetBSD/bind.platform.diff

this patch's macro condition expression is refered src/usr.sbin/bind/include/isc/atomic.h, but I dont check other archs.
