    Is there a reason why this line of code is invalid for amd64 (from 
/usr/src/contrib/bind9/lib/isc/x86_64/include/isc/atomic.h:25-28)?

#ifdef ISC_PLATFORM_USEGCCASM

/* We share the gcc-version with x86_32 */
#error "impossible case.  check build configuration"

    After doing some searching, all that that macro does is use says the 
OS can use gcc asm instructions.
