Resolution:
TIBCO Hawk agents can be executed from a NAS, network mounted drive, or attached hard-drive as long as it can access the software from a mounted drive.
TIBCO Hawk has different binaries for each platform. So it is not possible to share the installation across different platforms.

Each TIBCO Hawk components has it own startup configuration file.
HMA: hawkhma.cfg
Agent: hawkagent.cfg
Display: hawkdisplay.cfg
Event: hawkevent.cfg

Also, if you need to start the TIBCO Hawk Agents when machines boot up for different types of chipsets/OSs, you would need to create a 0batch/shell script that invoke the binary with the corresponding .cfg file.
