Issue in AgentX subagent on Big Endian architecture

Hi,

We are using Net-SNMP version 5.4.2.1 in our product and we found one issue with AgentX communication in the following scenario

AgentX Master agent on Little Endian architecture
AgentX Subagent on Big Endian architecture

In this setup we are facing an issue when subagent sends the AgentX Open-PDU then it can be seen from the capture that it is using big-endian encoding scheme and but the ByteOrder flag in the AgentX Open-PDU is not set. So while parsing the request received from the subagent the master agent is assuming little endian encoding, and hence causing the issue.
