i686 builds on x86_64 host on Debian 10 result in the RPC structs getting "__attribute__((packed))" annotations added to them. This is harmless since we know the XDR protocol aligns and pads struct fields suitably on the wire. Thus we can safely cull the attribute before doing the diff comparison. Signed-off-by: Daniel P.
